Where are the parentheses keys in the on-screen keyboard in iOS 15.4.1 when composing recipient phone numbers?

I know this might seem like the stupidest question of all time, but...:

In the the on-screen keyboard (such as in Messages app, for example) the two parenthesis keys ( "(" and ")" ) are available if you press the "123" button to get the keyboard with the numerals on it. The parenthesis keys are directly below the "5" and "6" keys.

HOWEVER, this is only true if you are typing the words in the body of a text message. But if you want to create a new message being sent to a new phone number that you have never yet sent a message to, and you click the little "New Message" square icon in the upper right of the screen, and the cursor then appears after the "To: " in the address line, then suddenly there are no parenthesis available in their normal place -- or anywhere else in the on-screen keyboard! At least as far as I can find.

The reason that this is significant is that I've noticed that when trying to type in a new phone number to send a text to, it often helps to type it out exactly in this format: " 1 (area-code) phone-number" -- just like that, with the parentheses included, and the hyphen between the prefix and the suffix -- rather then just typing in the 11 numerals without any formatting. When I send text messages from my Mac to new numbers, it sometimes won't work correctly if no formatting is included in the address line, but ALWAYS works correctly if you type it out fully formatted with spaces, parentheses and the hyphen.

But now on the iPhone -- that's not possible! Or it is? Where did they hide the parentheses in the on-screen keyboard for text-message addresses??? There are the brackets and curly brackets, but no parentheses anywhere obvious.
