Business Process Setup tab missing from Collaboration Messaging Configuration after 25A

We are currently testing the 25A release in our lower environments.

I noticed that in the 'Manage Collaboration Messaging Configuration' config task, the 'Business Process Setup' tab is missing:

Is this happening to others and is it expected? I don't recall reading about new features in 25A that would have any impact on this.

Thank you,
