Add an always-scan mode

[fttx]

We've been using your great app since the pandemia as time checker for employees succesfully, now we're back on normal times and have an issue with the app not noticed before since we all start the shift at the same time and now that doesn't happen anymore. The issue is that the app closes the camera about 15-20 minutes after last scan. So I want to know if there's a way to avoid / configure this behavior on the app.

camara turns back to list we have to open camera icon very often. That's why my request of such feature.

Fix: auto-click the camera button?
