Tl;Dr: I need to open deep link connected to a phone call from html page on Android. It MUST be the deep link, not the "tel:..." Url.
I've made simple mobile-friendly html page, with openstreetmap, showing gates around my residential block. Any gate could be opened by calling specific phone number, so, I've added map points, each having <a href="tel:+1234567890">open</a> link, that get opened by my android calling app (Google Phone), and gives ability to open the gate which is near me (on the map).
This solution is simple and workable, but it requires too many interactions, also, from time to time, after Google phone got open from the tel: link, the phone number isn't entered in the dialer (some kind of bug).
With specific command in Google Phone menu, I've created desktop shortcuts with the same numbers, and they are making the call by a single finger tap.
Now, I want to combine this two methods, as shortcut on Android desktop should be using some kind of deep link to the call app, but I don't know how to get the link that is used in shortcut.
Are there any tools/methods to see the actual deep links used to create shortcut, and use it in my html application to make it open immediately without opening Google call app dialer?
Googled a lot, tried different tools but no luck
