Clock App Has Disappeared from Settings

I am trying to coordinate my devices, and online I am told that if I have signed into iCloud on all my devices (the SAME iCloud account) then my Reminders and Clock App alarms should be synced. This is not true. They are not synced. I set an alarm on my MacBook Pro (fully updated) and if it goes to sleep the alarm doesn't go off on my computer, nor does it go off on my iPhone (fully updated). I look at the support information I can find and it tells me to go to Settings and look at my Clock App. I have just discovered there is NO CLOCK APP in Settings anymore. I have no idea how this is ever supposed to work.

The problem here is that there is an expectation set up by the fact that iPhone Mirroring is an app on Apple now, and it came with my computer. If I can open my iPhone screen in a window on my MacBook Pro then one would think that setting an alarm on one device would transfer that alarm to the other devices, or that I could at least DECIDE to do that if I wanted to. I can't even find my Clock as an app in Settings anymore, so it is hopeless to even attempt to coordinate alarms. What this means is that about half the time I try to set an alarm it doesn't go off, which pretty much negates the point of having the ability to set alarms on any device really. If this $4,000 computer can't function as an alarm clock then I have to say I am not impressed with its abilities as a computer. I feel like some functionality that was previously there has been removed and I am truly baffled why. I can't see any reason why removing access to the Clock App would be an advantage.

I asked Siri to tell me how to coordinate my iPhone alarm settings and my MacBook Pro alarm settings, and Siri first told me I would have to have a third party service like Microsoft Outlook or Google Calendars do that for me. Then I asked again a slightly different way and Siri got ChatGBT to come up with an answer for me. I was told that I just had to be signed into iCloud on both devices and that it would be effortlessly synced. Well, it isn't and I can't even find the Clock App as an item anywhere in Settings. I can't even find it by searching. All I get is ways to decide if the clock in the upper right hand corner is going to display seconds or not (and yes, I like the option to display seconds now...thank you, Apple).

So I am lost. Both these devices are factory reset by Apple as of this month. These are not some weird settings I have, they are the most up-to-date settings that Apple has for 15.2 on my MacBook Pro and 18.2.1 on iPhone. Why can't I trust my devices to make sure I wake on time for events I need to be awake for? I know that I have previously set up the apps to wake me EVEN IF Focus or Do Not Disturb was on. I can't even change these settings though, since "Clock" is not even in Settings on my MacBook Pro to say I want to allow it to wake SOME device from sleep.

I have to ask, does anyone want their alarm not to go off when they set it? Why would I set an alarm and not expect it to go off? If my computer goes to sleep or is turned off, then that would be fine if my iPhone also was set to go off. If they don't transfer information when I set an alarm though, then they will never be able to wake me.

I am aware I am over explaining this, but it seems like it has to be clarified because all the answers I have received so far have felt much more like they were meant to evade solving the obvious issue. I want SOME alarm to go off when I have set an alarm to go off. That seems like something everyone on Earth would want as a feature. I am sitting with four expensive Apple devices within arm's length of me. Surely I should be able to count on at least one of them to wake me up from sleep.
