### What's wrong with the content?

As fas as I know all Experience Cloud organizations will automatically have access to Schemas, Identities, and Datastreams. These tools will be free of charge for any DX customers including anyone who doesn’t currently have an AEP license.
With this new access a new permission was added in Admin Console for Datastreams. If an Experience Cloud user can’t see Datastreams in their UI it is likely due to missing permissions.

### What changes do you propose?

Delete the section that I highlighted to as it is not longer needed

### Anything else that can help to cover this?

_No response_

Open the linked Configure Datastreams documentation page and locate the passage about needing Customer Success Manager provisioning. Remove that outdated section, then review the page to confirm it no longer says organizations must be allowlisted through a CSM.
