Zoom support for hyperlinks?

I've found Linux support to be poor, to put it mildly.

I have Slackware64, and reduced to the 'other Linux' stuff from their website, which gives me no instructions whatever. I also have the firefox plugin.

The thing I want to do is join a meeting clicking on an invite.
From scratching around, I find the fi9refox plugin only organizes a meeting, but cannot join one. The download is somewhat erratic.

• /The binary zoom figures out my system, cpu, Window Manager, Graphics, and then segfaults.
• The zoom.sh script usually starts an argument about the name of the core-dump file, then runs the 'join meeting' dialog, spewing errors as it goes. But it does the business for joining with an ID, & password. It's apparently a debug mode.
• /opt/zoom/zoomlinux silently opens 2 dialogs. One is the 'join meeing' dialog the other confirms I want to send zoom news of this awful crash. I press "don't send" and it vanishes.
• ZoomLauncher throws a full page of what my box is, lists the 987 OpenGL extensions my card supports, reports on an argument with some .svg
  finally gives up the 'join meeting' dialog. Mark whatever newbie programmed that down a grade for not piping all the unwanted detail to /dev/null

I just want what any sane person wants - to be able to click on a link with encrypted password and join a meeting. Linux is big into encryption/decryption. Just look at the kernel config. I can do it on an Android - why not linux?

EDIT: Finally noticed it dumps some little icon in the taskbar Weird. So I can join painlessly. Still no hyperlink.
