How to use bootstrap icons in lizmap popup?

Hi,

I would like to insert bootstrap icons in my popup but I can’t do it…
With lizmap 3.6 I was able to display fontawesome icons by adding a link in the tooltip html:

<link type="text/css" rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css" >
Then I use html tag with class, for example. :
<i class="fa fa-globe fa-fw w3-margin-right w3-text-teal"></i>

Since I have a new version of lizmap 3.8, my old projects are still OK (the icons are shown) but when I use the same code for a new popup, the icons are not shown. :sleepy:
I’m trying to add custom CSS but no luck.

So I try to use bootstrap icons because LWC is based on this technology but I can’t do it either.

Could you please help me ?
