Long story short: I discontinued their program and it's been 2 years and I still receive those action required emails only to find out that there is absolutely no action required on my side. Harassing users is their favorite past time I swear. Ask the Github desktop folks. On Mac OS, there is no option to disable automatic updates. It loves installing a helper that runs 24/7 with admin privileges. If you click on deny, it will keep harassing you - every. single. day. First thing in the morning - 3 times, 3 times in the evening. You could be in the middle of something important, like a meeting or a screen share or running some serious stuff like CNC milling (which I do) and this thing will just popup and ask you for admin privileges until you accept.
And even if you accept and give it permissions, it just buys you a few days time. People have tried before to open an issue on Github - their response was simply "This isn't a priority for us right now" and they just closed the issue.
Same story with Windows too. I wish there was a law to prevent this kind of bullying behaviour.
