[AppService] what does `Csm` mean in `CsmPublishingCredentialsPoliciesEntity`?

In appservice's swagger, we have the `basicPublishingCredentialsPolicies` resources using `CsmPublishingCredentialsPoliciesEntity` as a response, where the `Csm` reads like a typo for `Scm`.

Could we know what does the `Csm` stand for here or it is just a typo?

Start by locating the AppService swagger definition for the basicPublishingCredentialsPolicies resource and its CsmPublishingCredentialsPoliciesEntity response. Check the surrounding naming and history for whether “Csm” is intentional or a typo; done means the naming is confirmed and the issue has a clear explanation or correction path.
