Can't disable app on startup

Hi everyone, I’m having a problem with an app that I just installed (Meta quest link), every time I turn on the computer the app opens by itself. Obviously you would tell me to go on "task manager" to disable it at the "startup" page but the problem is that it does not appear. I also tried the windows settings but the app does not come out there either, I tried to see if in the settings of the app there was any option that made it start by itself but even there I did not find anything. I don’t know what else I can do: how to disable this app on startup?
