Any free group chatting app for 20 members for PC -no phone connection-?
Ms teams and Google meet only permits 60 minutes per meeting. Switchboard only 10 people for free version.
I only need a meeting app for about 20 people to be able to chat prolonged time and sometimes voice chat. And it has to have a notice sound so that another participant can be notified via sound and/or pop-up screen when needed.
Thank you in advance.
