Best of luck...
I struggle to get anyone calling at my house to ring the doorbell at all, never mind follow written instructions on its use
Sorry, I may be slightly prejudiced, now being on the second brand new (wired) bell, and third brand new wired bell push in less than 18 months.
When the last one simply stopped working, I 'went nuclear' and fitted one of these. It remains to be seen how long this lasts until it fills with water and dies, but ironically, since installation, no one has called here.

BTW, ignore the nonsense product description and reviews, it is definitely a momentary 'push-to-make'
