 Some background - I had a Raspberry Pi Zero W set up with WiFi and Raspberry Pi OS Lite. I could already hit it with SSH and copy files over. I'll suggest that this will be easier if you install the full Raspberry Pi OS, however this guide is for a headless Pi.

 Now I was able to run the app, connect my phone to is and see a blue dot! Pressing it will show the text on the console. Hooray!
