Update not allowed in MondoDB Realm

Hi everyone!

I’m using MongoDB Realm and Angular as a framework. I can create, read and delete documents with queries/mutations of GraphQL and using the API of MongoDB Data Access but I cannot update the documents.

I tried with the GraphQL endpoint and I can use the upsertOneUser but not the updateOneUser (and the others update functions). It says that it is not allowed. Also using the collections it does not work.

Whare is the problem? I have all the permission for write/read/insert documents.
