How can I get data from the server posing as a mobile application?

Question

Android

There is one mobile application, when requesting information in the application, it accesses the server and displays a response.
How can you pretend to be an application so that you can receive a response from the server?
I installed the application in the emulator and with the help of wireshark I found out where the application is accessing, however, the request goes through the SSL protocol. I can't imitate it without keys. The keys are wired into the application, most likely, because I did not find any keys in the system files.
Perhaps there is some way to install an emulator on Linux that can be conveniently managed and write an external script to control the emulator and get information? Please tell me if someone knows.
