Currently, the Atlassian Teams feature in Jira Cloud only allows teams to be linked at the project level. There is no option to link or display teams at the board level. This limitation means that users cannot easily associate a specific board with a team, which can be confusing for organizations that have multiple teams working within the same project but using different boards.

Desired Behavior

• Allow teams to be linked directly to Jira boards.

• Display the associated team(s) on the board view.

• Enable filtering, reporting, and permissions based on board-level team associations.
