Hyperlink in Chat Not Clickable

Links in the Zoom chat are not clickable by default. You could copy the link and email it to them separately. There is a also a Zoom marketplace app, Salepager, for emailing attendees and including a hyperlink.

Zoom for Linux will only render the links as clickable if they appear on a new line in the chat message. If they are placed in-line, they will be rendered as text.

This is different from clients on Win and Mac, which render the links as clickable regardless of their placement.
This is a serious shortcoming since many webinar moderators disable chat Copy functionality and rely on the participants being able to click the links in the chat.
