Send daily email using a multi choice column in Sharepoint

Hi,

I am trying to create a flow that would send a daily email with the following conditions:

1. A column named "follow-up", with a multi-choice that consists of people name and different comittees that I would have a follow-up to do regarding the item.

2. For every item that "follow-up" is not empty, the email would list by "follow-up" choice, which item I would have to follow-up.

3. The "follow-up" choices are not static; from time to time I need to add a new choice so in the flow it can't be filtered with pre-determined choices.

4. Some items have a "due date", which would be included in the email

Example:

Email: "Daily follow-up elements"

Follow-up choice 1

Item 1 

Item 2 due 2022-12-05

Item 5 due 2023-01-08

Follow-up choice 2

Item 2 due 2022-12-05

Item 4

Follow-up choice 3

Item 1

Etc...

I read a lot on the subject but wasn't able to find something that would solve what I need to do.

Thank you!
