To restrict a group chat in Facebook Messenger, the platform does not currently offer a direct "Restrict" feature for group chats in the standard Messenger app. However, there are several effective alternatives and workarounds you can use:

Methods to Restrict or Manage Group Chats in Messenger

• Mute the Group Chat:
  You can mute notifications from the group chat so you won't be disturbed by new messages. To do this, open the Messenger app, find the group chat, long press or tap the info ("i") icon, then select "Mute" and choose how long you want to mute notifications (from 15 minutes up to indefinitely). This effectively restricts notifications without leaving the group

• Ignore Messages (Similar to Restrict):
  On the desktop version or using the mobile browser in desktop mode, you can open the group chat, tap the share icon or options menu, and select "Ignore Messages." This moves the group chat to your spam folder, stops notifications, and hides the chat without notifying other group members. This acts like a "restrict" for group chats

• Report and Ignore via Facebook Lite or Desktop:
  Using the Facebook Lite app or the desktop basic version of Facebook, you can open the group chat, go to group settings, select "Report," choose "Other" and then "Spam," and finally select "Ignore conversation." This mutes and restricts the group chat from bothering you

• Leave the Group:
  If muting or ignoring is not sufficient, you can leave the group chat entirely by opening the group, tapping the info icon, then the three-dot menu, and selecting "Leave Group"

• Mute or Block Individual Members:
  While you cannot restrict individuals within a group chat directly, you can mute or block specific members outside the group to reduce disturbances

Summary

Method| How to Do It| Effect
---|---|---
Mute Group Chat| Open group chat > Info > Mute > Choose duration| No notifications, still in group
Ignore Messages| Desktop or browser mode > Open group > Ignore messages option| Group moved to spam, hidden, no alerts
Report & Ignore| Facebook Lite or desktop > Report > Spam > Ignore| Mutes and restricts group notifications
Leave Group| Group info > Three dots > Leave group| Exit group, no messages
Mute/Block Members| Long press member profile > Mute or block| Stops messages from specific users

These are the practical ways to restrict or limit interruptions from group chats in Messenger since a direct "restrict" feature for groups is not broadly available

. Muting or ignoring the group chat is the most common and effective approach.
