I just enabled dynamic related lists in my Opportunity lightning record pages, removed the Related Lists (plural) component, and tried to use the Dynamic Related List - Single component to expose Opportunity Contact Roles.
I could not find Opportunity Contact Role as a choice in the Related List field of the Dynamic Related List - Single component.
How can I make Contact Roles visible after turning on dynamic related lists?
Or is that not possible (yet), and must use the Related Lists component just to expose Contact Roles via the old page layout?

Dynamic related lists are supported for key objects (Contact, Account, Opportunity, Lead, Case), custom objects, and hundreds of other standard objects in Salesforce. However, some objects are not yet supported. Salesforce will continue to make additional objects available to use with dynamic related lists over time.

I couldn't find a specific list anywhere, but I guess this is just not a supported standard object at this time.
