Hey,
you could try splitting the flow into 2.
First flow creates a row in SharePoint with a status column and emails the leader that there is a pending request.
Here you could then either create an easy canvas power app where they can approve/reject pending requests. Or just let them update it via the SharePoint list (you can link to the specific item in the email to SharePoint).
Then have another flow, that triggers on changes with a trigger condition if status is approved or rejected, which then emails the requester the result.
