Installed app (apk) not showing up

Hi again,

So I am able to test by wifi and usb with the companion, I am able to install a Makeroid .apk with adb install …, or even with a QR code, the app is visible in the ‘application’ settings, but I cannot see it among other, already visible applications on the ‘main’ screens of my phone. Hence I cannot install it on my parents’ phones, and launch it in a ‘regular’ manner.

What did I miss?

I checked the forums, the web, the doc, the video, the faq, to no avail, I might have overlooked something…
