Teams user, who is an owner of the Team, cannot add a Planner tab to a channel.
This is a known issue: https://docs.microsoft.com/en-us/microsoftteams/troubleshoot/known-issues/teams-owner-cannot-create-planner-tab
Adding the user as a member to the Microsoft Office 365 Group, used by the Team, fixes the issue.
