B4X FEED Link in a webview dont open an app

[practicalsoft]

I open a web Page by a webview.
In the HTML i ve a link (a href) that point to an Istagram profile.
I would like to open Istagram app at the selected profile.
In Chrome It works, in the webview It opens the Istagram website.

I ve also tried something like this (googling stack overflow).
<a href="fb://profile/fbID">Facebook</a>
<a href="twitter://user?screen_name=username">Twitter</a>

Is maybe something related to manifest?
Is It a good idea to have a button outside webview to open Istagram app if istalled?

Hoping to have explained the problem clearly.
Thank you.
