I saw that CosmosDB can be accessed via any supported api regardless of whether it's set up as a GraphDB first. <https://learn.microsoft.com/en-us/azure/cosmos-db/mongodb-introduction> I see the example where I can run a SQL query against the graph database - but how do I get the MongoDB api connection string for it? 

Since it was set up as a graphdb api from the start, the mongo db connection strings don't appear in the settings like so: <https://learn.microsoft.com/en-us/azure/cosmos-db/connect-mongodb-account#GetCustomConnection>

Instead I only see the keys settings.
