How to recall or delete approval request if request cancelled

[ShineTan123]

Hi All,

I have a flow to request approval based on SPL changes, it will send attachment in SPL via email to approver, and also send approval to approvers at the same time. 

But It happens that when the flow was triggered-meaning email has sent to requestor and approver get the approval request, but the requestor need to revise or delete the original request, so how can I build the flow to recall or delete those requests sent to approvers already?
