Can we restrict visibility of ms teams button in atto editor?
are there any useful plugins that help us restrict visibility of buttons in atto?
You can't restrict by user without a lot of work, but you can simply remove the icon from the toolbar. Go to Site administration > Plugins > Text editors > Atto HTML editor > Atto toolbar settings (https://yourmoodle.org/admin/settings.php?section=editorsettingsatto) and edit the "Toolbar config" field to replace "links = link, teamsmeeting" with "links = link". See screenshot below.
