Help with creating a shortcut/automation to show today's calendar events and reminders

Hello all. I'm driving myself crazy trying to create some shortcuts and automations so I figured I'd put an ask out to see if anyone more experienced can help.

I would like to create a shortcut that pulls events from a shared calendar (with timings), events from a personal calendar (with timings) and reminders from a shared reminders list (with timings) and sends this information daily to someone through iMessage. The format I imagine looking like this:

Today's Events:

Event 1 - 8am to 9am

Event 2 - 9am to 10am

Today's Reminders:

Reminder 1 - 8am

Reminder 2 - 9am

Today's Schedule:

Event 3 - 8am to 9am

Event 4 - 9am to 10am

If there are no reminders or events it would be good to state that with something like:

Today's Events:

Not Applicable

I would also like to create a shortcut that asks me (at 6pm) which tasks I would like to work on the following day and gives me the option to pick from a list in the Numbers app, then create a calendar event using this in a designated time I would have already blocked out.

Thank you in advance!
