Change status field after review time expired

Hi all,

I have table as below

Text field: Request
Multiple choice field: approved (no and yes)
Date/time field: approved date (dynamic form > when the record is save and approved is equal to yes, change approved date to current date time

Multiple choice field: Review status (expired review, successfully reviewed)

When the approve field is approved and approved date change to current date/time for example 27 June 2020 07:00 AM, i want to setup 24 hours expiration for for review, so after 24 hours the status field is not changing, the review status will be expired status. Also if it’s possible to setup reminder for example 6 hours before expired?

Many thanks
