Here is an example where I started to setup a Google Drive:

php occ files_external:list
+----------+--------------+--------------+---------------------+----------------------------------------------------------------------------------+---------+------------------+-------------------+
| Mount ID | Mount Point  | Storage      | Authentication Type | Configuration                                                                    | Options | Applicable Users | Applicable Groups |
+----------+--------------+--------------+---------------------+----------------------------------------------------------------------------------+---------+------------------+-------------------+
| 1        | /GoogleDrive | Google Drive | OAuth2              | configured: "false", client_id: "qwertyuiop", client_secret: "***", token: "***" |         | All              |                   |
+----------+--------------+--------------+---------------------+----------------------------------------------------------------------------------+---------+------------------+-------------------+

So that has configured client_id client_secret and token in the "Configuration" section.

So you could do examples with keys like that.

Somehow files_external:list knows to report the value of some keys as *** and not show the secret values. So that will also let you test the files_external:list --show-password command option.

Also test the output of occ files_external:config 1 key_name (not providing a value). In that case it is supposed to display the existing value.

Other ideas might be here: https://doc.owncloud.com/server/admin_manual/configuration/files/external_storage_configuration_gui.html

Looking good.
Please rebase and squash when you do the little changes. Then we should be able to merge.
