How do I open Audacity on RPI Startup?

Does anyone know how to open apps (like Audacity) on Raspberry Pi start up?

Install Audacity on Raspberry Pi | Pi-Apps
I never used it on Pi… but try the link above for info

I already have Audacity … I’m just trying to open it with python on startup.

Are you now following your other thread…?? run from Python

Yes. I am because my other thread is very vague. Because it would explain how to open Audacity but not on startup.
