The add-in is now assigned to the users/groups you selected. For newly assigned (or removed) users, it may take about a minute for the add-in button to be shown (or removed) from their Office apps, and users may need to restart their apps for changes to take effect. For best adoption of the deployed add-in, it is recommended you send an email to the users/groups explaining what the add-in does and why they should use it.
