@akhterwahab Do you think you can add other extensions suggested in #2067? Otherwise, we can merge this as is and include additional extensions later.

Ping @akhterwahab :)

hi @Gallaecio Maybe we can merge these and add other extensions later on in another PR

[Gallaecio]

I’ve added the additional extensions myself using the GitHub editor since it was trivial to do.
