There are two users each with phone number security set to (nobody,my-contacts) - "Users who add your number to their contacts will see it on Telegram only if they are your contacts". How can these users add each other as contacts assuming they know each other's phone number? Without changing their security settings and allowing third parties to add them as contacts. Is there a way to allow an exception to the phone number security rule for non-contacts, if two non-contacts want to add each other simultaneously by phone number?
