Hi @tested1,
I assume that your scenario could be achieved by a flow likes below.
1.From your description, it seems that requesters will submit their requests in a list. Add the trigger When an item is created in SharePoint list.
2.The request will be reviewed by an IT team, add an action Start an approval for the first approval.
3.IT team send the request to director, add second Start an approval action.
4.Form then goes back to IT Team. If the approval response is equal to Approve, send an email to IT team to give authorization, then send another email back to the requestors to notify them.
A screenshot for your reference.

Best regards,
Mabel
