Using IMongoQueryable on unit tests for Async methods

.net 6 Mongo.Driver
I need to test async methods for mongo, which requires use of IMongoQueryable, but to use methods like FirstOrDefaultAsync, Where, etc, I need to have a valid IMongoQueryable.

Today I need to mock a mongodatabase just to create that for tests and it’s taking a lot of resources and changes on my automation process.

How do I test that?
