App development workflow

What is your workflow to test an app? I think I'm doing it wrong. I do:

• change local code
  
• Use GitHub Desktop to commit changes
  
• Push changed to "master" - I think, that's my forked repository
  
• Wait for Actions to finish
  
• Go to https://MY_NAME.github.io/BangleApps
  
• disconnect gadgetbridge
  
• connect to Bangle.JS
  
• uninstall the app
  
• re-install the changed app
  
• disconnect + reconnect to phone
  
• send a message
  
• see it doesn't work
  
• try not to curse
  
• repeat
  
  

I'm messing with the 'messages' app, so I need to test notifications from gadgetbridge
