How to get started

First of all, make sure you have deployed Safe Doc and read how to Configure Safe Doc.

Case 1: Block all chats

If your ultimate goal is to completely ban the chat feature in Google Meet, add and set the policy BlockMeetChat to true in the Safe Doc extension policy configuration. Save and verify if it works. The chat feature is not blocked if the policy is not set or false.

"BlockMeetChat": {
  "Value": true

Case 2: Block single student's chat with the magic /chatoff command

It's also possible for your teachers to temporarily ban a few students from flooding chat messages disturbing the lectures.

Ask your teachers to use the magic /chatoff <student email> command in the chat window to disable the given student's chat feature for the lecture session. Take a look at the following example.

  1. (The chatty student Pat Paul): types tons of chat messages disrupting the classroom.
  2. (The teacher): finds the email of annoying student.
  3. (The teacher): opens the chat window and types
  4. (The student Pat Paul): my chat bar is confiscated!
  5. The classroom returns to silence and focus.
Safe Doc's /chatoff command allows teachers to block individual student's chatting in Google Meet

The /chatoff command is managed by the Safe Doc policy EnableMeetChatOffCommand. If the policy is not set or false, the /chatoff command is not enabled. If the policy is set to true, the /chatoff command is enabled. Here is the policy setup.

"EnableMeetChatOffCommand": {
  "Value": true

Caveat: students are also able to initiate the /chatoff command which disables the chat feature of other students.
