Navigation for app that is embedded into another app’s user interface

I have an app that is going to be embedded in another app. The app we're embedding into has it's own navigation system (bottom navigation and may have a hamburger menu at the top).

Attached below is an example of the experience.

My app also has a bottom navigation and therefore there are 2 bottom navigations:

This does not seem like an acceptable option, and therefore I was thinking a top hamburger navigation menu would be ideal but they may also have a hamburger in the same corner, which is not ideal.

I'm wondering if anyone has any ideas how to add navigation in this embedded environment.

Thank you.
