Trouble adding meeting

I read that I should be able to add a meeting by adding a WP Bakery block. However, when I click + to add a new block, the only options when I search for Zoom are “Zoom Meetings/Webinars Grid” and “Zoom Webinar.” There is no option to add just a Zoom meeting.

So I tried using the shortcode [stm_zoom_conference post_id=”{}”] as given in the settings, but I’m not sure where to insert the meeting ID. Nothing shows up when I insert it as either of the following:

[stm_zoom_conference post_id=”89350246893″]
[stm_zoom_conference post_id=”{89350246893}”]

What is the proper way to insert a meeting via shortcode, and/or how can I get it to show up as one of my WP Bakery element options?
