File sharing in Manjaro usually requires additional packages that may not be installed by default. These may be helpful:
I’ll just add that in a freshly installed Gnome VM, all file sharing options seem to be in place awaiting activation. I imagine you may have inadvertantly removed needed packages at some point, or neglected to attend to required maintenance and/or updates.
Either way, working through the articles (previously linked) should get you back on track; barring unexpected circumstances.

System Information
While information from *-fetch type apps might be fine for someone wishing to buy your computer, for Support purposes it’s better to ask your system directly; 
Output of the inxi command with appropriate parameters will achieve this (naturally, formatted according to forum guidelines) and will generally be more useful for those wishing to help:
inxi --filter --verbosity=8
or the short form:
inxi -zv8
