Firefox extension can't connect to natively installed package

I have installed the addon uGet Integration. It is supposed to detect the natively installed package uget-integration and launch the uGet download manger using it whenever it detects any downloads. But the extension (uGet Integration) can’t detect the natively installed module (uget-integrator). This happens on Firefox snap version, deb edition of Firefox works fine. As it seems that it is considered a normal behaviour of snap apps; I’m planning a bug report to extension & wrapper development page. Is there any workaround to this issue?

This looks similar to https://bugzilla.mozilla.org/show_bug.cgi?id=1462888.
