What happens to the approval process if an approver is inactive or gets deleted from the organization?

If an approver is inactive or deleted from an organization, users with admin access will be able to approve the transaction instead of the inactive/deleted user.

Similarly, if an approver is a part of the multi-level approval process is inactive or deleted from the organization, the transaction will remain the same. Users with admin access will be able to approve the transaction instead of the inactive/deleted user.
