Your method of adding a table should work just fine with some modifications.
instead of creating a table with the objects being { Value: “display name” }
Make this be the object for each of your people and substitute the equivalent SharePoint profile data for them.
{
Claims: $"i:0#.f|membership|{fxUserProfile.userPrincipalName}",
DisplayName: fxUserProfile.displayName,
Email: fxUserProfile.mail
}
you can do a search based on email address too, using the Office365Users connector and it will return a similar object for you searched user.
