Hi @Sebastiaan1,
I don't think you need to change your schedule trigger action. I think you can just execute the following steps.
1. Remove the When an item or file is modified trigger action
2. Add a Get files (properties only) action
3. Configure it to use your existing list
4. Add the expression I shared earlier to the Filter Query field. You can add the expression in the filter query field via the add an expression button and copy pasting this expression:
4. Add the expression I shared earlier to the Filter Query field. You can directly paste this in the Filter query field. Without having to use the add an expression button.
Modified ge '@{formatDateTime(utcNow(), 'yyyy-MM-ddT00:00:00Z')}'
Hope this makes it a bit clearer what I was trying to propose. If you need any additional help just let us know.
Update: Changed my mistake in step 4.
