Power App - Multi Step Approval Process (With in Canvas app)

Job ID: 35528372

Budget: ₹1,500 – ₹12,500 INR

I want a Power App in Canvas App to be designed, for the Approval Process.
Scenario :
1. It is 4 levels of the Approval Process. level 1(manager) -> level 2(Sr. manager) -> Level 3(Admin) -> Level 4(HR)
2. now a requestor will create a request, fill in some mandatory columns, & choose all 4 levels.
3. now, it goes routing at each level.
4. big point - keep in mind - that if a request gets rejected at the 3rd level, then it should go back to the requestor to revise the same request, but not from scratch, from the 3rd level because 1st & 2nd already approved the request, also I don't want to delete any information, from SharePoint.

Ping, to discuss more.
