As long as a PDF is okay for "sharing afterwards", yes.
As for "sharing live" ... I use goMarkableStream for this. You view the tablet in a browser window, and you share the browser window using whatever video sharing software you're already using for the meeting. It works by talking directly to the tablet and does not require a reMarkable Connect subscription or an internet connection (i.e. it can work over a USB cable).
Just be sure to install the correct version of goMarkableStream, depending on the firmware version in your tablet. There are now three different ways for software to access the screen's contents, and each version of goMarkableStream implements only one of them. This is explained on the Github page where you can clone the repo and/or download an executable.
