Speech Manager by Command 'scoreboard'

The mod adds server commands that manage speech through the scoreboard. Chat can be limited so that only teammates, or only players outside a team, see a message. A shouting command can be prohibited or allowed, and a command can let players send text to people who are otherwise banned from chatting. Scores can be set on the scoreboard to control these permissions. Only the server needs the mod, and it requires Fabric API.
