Cloud Snapshot Manager Login/Auth instructions

Hello

We are trying to automate the creation of cloud accounts in CSM.

We found this API we can use: https://developer.dell.com/apis/5788/versions/latest/api/cloud-accounts-v1.yaml/paths/~1v1~1cloud_accounts/post

However we are missing the docs about how to retrieve the auth token. The only reference we see is this broken link:
"Refer [Authentication](/token/token/postauthoauthv2token) section for more details about generating the access token."

How can we generate this token?
