Currently, there are two different action types with different roles assigned for the `listDatabases` command and the `$listDatabases` aggregation stage. The roles assigned for each action type are the following:

`listDatabases` action type (`listDatabases` cmd):

• readWriteAnyDatabase
• readAnyDatabase
• userAdminAnyDatabase
• dbAdminAnyDatabase
• clusterMonitor
• backup

`aggregationListDatabases` action type (`$listDatabases` aggregation stage):

• clusterMonitor
• clusterManager

Since it is expected that all the roles that can execute the `listDatabases` command can also execute the `$listDatabases` aggregation stage, the action type for both should be the same and should be assigned to the roles that were initially assigned to the `listDatabases` command.
