Do i need upgraded account to add multiple slack workspace?

Hi, I am trying to integrate a new slack workspace, but i see this error instead of the add workspace button. Do i need upgraded account to add multiple slack workspace ?

@vanna1 Hi there. A few months ago we changed our pricing plan so Slack is only available with a Team plan and above. Your existing installation was simply grandfathered in; it doesn’t have anything to do with multiple workspaces. More details on pricing here: https://sentry.io/pricing/
