MongoDB: Why always report non-authorized error when try to manage users in one database?

Question

all, I am new to mongoDB, and recently I am trying to set up a local env to try it, below is my step:

1. Use docker to create a mongoDB container:

   docker run -d -name my-mongo -p 27017:27017 \
     -e MONGO_INITDB_ROOT_USERNAME=admin \
     -e MONGO_INITDB_ROOT_PASSWORD=Asdf1234 \
   mongo:4
   

2. Then I use Studio 3T software to connect the admin database, and adds a new user named leon, below is the role I granted:

3. Then I create another database with the user leon :

4. Test the connection, the result is OK:

5. Connect to the new database, and right click on the Manage users menu:

6. But it always reports the non-authorized error:

Does anybody know the detail reason ?
