We are developing feature that allows users to add identity verification to envelopes. And there's a checkbox which is called "Allow recipient to provide phone number" We need to decide when to show that checkbox, because not all accounts have access to the checkbox. From documentation (https://developers.docusign.com/docs/esign-rest-api/reference/accounts/accounts/listsettings/) I see that there's phoneAuthRecipientMayProvidePhoneNumber field which allows to determine that thing.
When I open the page for envelope creation I can see that the checkbox is available but API returns false value for that field. So we can't really decide do we need to show that field or not. It seems like a bug in API.
