"In-meeting chat" only participation

[TobyR]

Is it possible for people in one room (with VC facilities), who are in a Zoom meeting, to see and participate in the in-meeting chat, without having to fully dial in?  I appreciate they *could* dial in and mute their video and sound, but they would still be getting an incoming audio and video feed, and if there are many people in the room and the site does not have great Internet then that could still be an issue.     FWIW I'm using 5.16.10 and have a paid-for/business account.
Thanks in advance.
