Best practices for enterprise connections with Auth0 Organizations: Single or multiple connections for B2B customers?

I’m using Auth0 Organizations for a B2B web application. When I add an enterprise connection (in this case Microsoft Entra ID / Azure AD) is it best to add a new connection for each customer, or one connection that serves all customers who are using Entra ID?

There don’t appear to be any settings at the connection level that are customer-specific, and users are still associated with Organizations to keep them separate. Making a new connection for each customer could also result in a very large number of connections. I’m inclined to just have one connection with Entra ID that serves all customers – is that the recommended approach? Are there pros and cons?

Apologies if this is documented somewhere, but I wasn’t able to find anything directly related to it. Docs that are relevant, but don’t answer the question:
