This argument is required for a custom cloud and usually unnecessary otherwise. Defaults to the authority
matching the "Azure: Cloud" setting in VS Code's user settings or, when that setting has no value, the
authority for Azure Public Cloud.
:keyword str tenant_id: ID of the tenant the credential should authenticate in. Defaults to the "Azure: Tenant"
setting in VS Code's user settings or, when that setting has no value, the "organizations" tenant, which
supports only Microsoft Entra work or school accounts.
:keyword List[str] additionally_allowed_tenants: Specifies tenants in addition to the specified "tenant_id"
for which the credential may acquire tokens. Add the wildcard value "*" to allow the credential to
acquire tokens for any tenant the application can access.
