I mean not channels, I want to integrate some workspaces. If one slack workspace has been integrated, Can I integrate another workspace?

Sorry, but integrating multiple workspaces is not yet supported on one form.

You will need to create another form for integrating a second workspace.

We could check if this can be escalated as a feature.

Do check and let us know.
