Out of Office SMS Auto Responder- keeping this active!

I am aware this has been posted before, but hoping to keep it fresh and see if any work is being done to release this feature any time soon. I have been using Android for year's. I bought an iPhone to use for business. I am seriously thinking of sending it back. There are SO many limitations!

But the limitation that is a big enough reason for me to go back to Android is that I am unable to set an Out of Office SMS auto responder text. With Android, I got an app where I could set a schedule for my working hours. Outside of those hours, my phone would be put on Do Not Disturb, and if anyone texted me outside of my working time, they would get my auto reply "Thank you for reaching out. We will respond during normal business hours of X-Y." This is critical. I don't want to spend weekends looking at my phone but I have to because otherwise my clients think I am being unresponsive and rude. I have looked into 3rd party apps for this like Open Phone or Message Keep, but it's an added expense plus I can't keep my number which I purchased because it has my business name in it.

I also tried the Focus idea- I set a Driving focus to send a message, but I need to manually turn this off and on. Any ways to automate this?? Hoping someone can think of something!! Thanks a bunch!
