Approval Flow Editing PDF with Signature

[Anonymous]

Hello, 

I am trying to create a flow that would support the automation of the following: 

- An invoice is received (PDF Format)

- It is validated by user 1 and the details of the invoice logged in a tracker (currently on excel but intending to move to a SharePoint list) 

- If approved, user 2 is notified that an invoice is requiring approval. If approved, the flow enables user 2 to edit the PDF by adding his/her signature and the date. 

- Once both users 1 and 2 have reviewed and approved the document, it is sent to a central function for processing. 

I have looked into flows via Power Apps as well as approvals within Flow and standard workflows on SharePoint but cannot find exactly how to process. Any recommendations would be greatly appreciated. 

Thank you!
