Feature Request: Add support for url scheme's

Feature Request

Add support for url scheme's. This gives us the option to open phone number directly in the Vialer / Voys app. (like Whatsapp https://faq.whatsapp.com/en/iphone/23559013)
For example:
<a href="vialer://call?number=+31612345678">Call 0612345678</a>.
(I know that it is possible to open the phone number directly in the app with the "long press" context menu. But this is not always understandable for users.)

If possible, also add this functionality with the same url scheme in the android version of this app.
(I can't open issues in the vialer android repository)
