Ahh thanks @Stennie_X !
Now that I have your attention, could I politely ask if you have Typescript <–> JSON Schema expertise - or maybe know someone at MongoDB?
Our team is still debating how to maintain Typescript interfaces and MongoDB JSON schemas. I tried to ask for inputs here, but to my surprise nobody answered 
I imagine this is a task everyone using Typescript/Mongodb-schema-validation would have, but there is supringsly few results when I google this.
