Advanced Power Automate multiple level approval logic

UI is PowerApps for submitting the request and approval process workflow is used Power Automate. Task created for all reviewers to manage the review process if it’s approved/rejected”

How can I Add additional reviewers after the approval workflow is InProgress?

I don’t want to apply timeout or reassign logic using custom connector or CDS.

If it’s possible to:-
Create a loop to check if task is not approved and original approver current approver then divert approval task to new approver.
