read receipts for messages

[BrilliantVoice]

Hey everyone,
I've read in the documentary that there's an option to enable "read receipts for messages" in Team-Chat. But I can't find the option "Visibility" or anything else like this in the settings. Is this a PRO feature? We're just a basic user (Version: 6.1.11 (39163)) on MacOS.
Thanks for your help.
Cheers, Sven

Hey there,
I can't see my last post, so I try it again. 
We're looking for the option to enable the "read receipt for messages" in team chat. I can find this feature in the documentary, but not in the settings of my account. Is that a PRO feature? We just have a Basic account and using Zoom Workplace Version: 6.1.11 on Mac.
Thanks for help.
Cheers, Sven
