View Button for approval, similar to Edit Button

Hello all,

we have the requirement for something like a "View Button" in the approval notification. Similar to the Edit button. The problem is, that the information within the approval notification is not enough, we would need an extensive overview of all data entered.

In the following scenario:

A line manager starts "Request new position". This triggers an approval to

Line manager (Requests Position) → HR → Line Manager +1 → Line Manager +2

In case the first approver (HR) makes any changes with the Edit button, how can the following line managers see all the data, but also the changes that were made? Only view, line managers are not allowed to edit.
