How do I enable the Meta Business Suite?

I've been added as an admin on a Facebook Page, and would like to use the Meta Business Suite Business Feed tools. However, my account appears to not have access to this nearly two year old product. Is there any way to get Meta Business Suite enabled for my account?

When I go to business.facebook.com, I just get the old Business Tools. I have no button to access the Meta Business Suite from the All Tools menu. I've compared my view to another person on the team who does has access, so I can see where the button should be but it's not there.

Also, if I attempt to load the Business Feed URL directly, I just get an error saying "Sorry, this content isn't available right now".
