ezgh iam groups add-members <group> <member>...Add users or bots to a group, one at a time, leaving the other members alone. A member is user:<user ID or email>, bot:<bot ID, slug or name>, or just the reference when it matches only one user or bot. Adding someone who’s already a member changes nothing; removing someone who isn’t is an error.
Part of ezgh iam groups.
Examples
ezgh iam groups add-members ops user:ada@acme.test bot:deployerFlags
This command also takes the global flags.
