unable to view attachments added by Approvers in supplier profile change Approval notification

Summary:

Hi Community,

We set up approvals for profile changes in the event that employees or the supplier through supplier portal modify the bank account.

We set up the rule "Parallel Approval First Responder Wins."

Approvers attach documents and approve them through the approval process, but these documents are not shown at the supplier level after approval

I have few questions regarding attachments

Is it expected functionality, if yes, are there any work arounds?

Which formats are allowed to attach and max size of attachments

How can users access to these attachments after approval for future reference, should we give any access
