Hi @Anonymous,
Unfortunately, there is no way to eliminate this limitation of the nesting level. Please refer to this document about limitation:
https://docs.microsoft.com/en-us/power-automate/limits-and-config#definition-limits
As a workaround, you can create a B Flow to receive the response of A Flow (the first Flow you create), to create more approval, for example:
A Flow -> HTTP request
When an HTTP request received-> B Flow
Firstly, you should create B Flow, after saving it, it will generate a URL:


Then create an HTTP post in Flow A, and paste the URL of Flow B into it:

Then Flow A will trigger Flow B after performing the last action, pass these parameters could do in the Body of HTTP action, you can use the method to create more levels of Approval.
