Sometimes a team member may forget to add their celebration dates to Matter, and it's added after the actual celebration date. Not to worry, Matter allows you to send a celebration manually.
Who can use this: Workspace Owners and Admins on the Basic plan and above, or on any plan during the free trial. Works the same for Slack and Microsoft Teams workspaces.
For an overview of the whole feature, read the Celebrations Guide.
How to Send a Celebration Manually
Go to the Web App.
Go to Settings, then the Members section.
Find the team member via search or scrolling and click Edit.
Go to the Celebrations section and next to the appropriate celebration, click Send Manually.
