The Microsoft 365 profile card (for OWA initially) lists the set of connected Viva Topics for a person. This only happens when the user has a Viva Topics or Viva Suite license. It’s an example of how Microsoft is building out the set of information available in user profile cards and embedding Viva Topics in as many places as possible. All good if you use Viva Topics!
