Hi,
We have multiple customers A, B, C set up as Organization X in Jira service desk CLOUD. When Customer A raises a request in the Portal, we can tag/mention him in the comments. However, we want to also tag Customer B,C in the comments, as they are from the same Organization.
Another interesting fact is that if any customer from org X leaves a comment on ticket; then agent can tag him moving froward from there.
And even if agent adds someone in 'Request participants'; still they cannot tag him in comments.
Another ticket had the same issue and got resolved by giving 'Browse user' permission but that ticket is not related to service desk CLOUD; moreover all of my browse permissions are setup correctly as shown in screenshot below.

Let me know how to tag/mention customers from same organization in JIRA service desk cloud?
