How to prevent Figma Agent to be added to Login Items

Every time I launch the native Figma app on macOS (macOS 13 Ventura) I get this notification:

Login Item Added: "FigmaAgent.app" will open automatically when you log in. You can manage this in Login Items Settings.

And following the instructions on the notification I can remove the Login Item as expected, but I will get the notification again next time I launch the app, and the Login Item will be added once more.

I want to remove it and never to be added again. How can I do that?

Pd: I reached out to Figma support a few times, and they mostly ignored my messages, and when I asked why was I being ignored they gave me a rather unhelpful answer:

Hey there, sorry for the delay & confusion. We didn't reply, because the answer was in your original tweet. Sorry if it wasn't obvious, but in the screenshot, you manage it from Login Items Settings: Apple menu > System Settings, click General in the sidebar, then Login Items.

To be very clear, I don't want to know how to remove FigmaAgent from Login Items, I want to know how to prevent it for being added again.

This seems to work for removing FigmaAgent:

• Force Quit it in Activity Monitor

• Remove it in System Preferences -> Users & Groups -> Login Items

• Delete ~/Library/Application Support/Figma/FigmaAgent.app

• Delete /Applications/Figma.app/Contents/Library/FigmaAgent.app

• touch "~/Library/Application Support/Figma/FigmaAgent.app" to stop it being re-enabled by updates
