$regex = '/^(https?://)?chat(?:.whatsapp.com/)([a-zA-Z0-9_-]{22})$/';//its working for without 'invite'​

I want the regex to support the following URL formats:

https://chat.whatsapp.com/FrTz7HJfmKjAROYZsfDrKQ
https://chat.whatsapp.com/invite/FrTz7HJfmKjAROYZsfDrKQ

https://chat.whatsapp.com/FrTz7HJfmKjAROYZsfDrKQhttps://chat.whatsapp.com/invite/FrTz7HJfmKjAROYZsfDrKQ​

You can try this:

^(https?://)?chat.whatsapp.com/(?:invite/)?([a-zA-Z0-9_-]{22})$

JavaScript
 
^(https?://)?chat.whatsapp.com/(?:invite/)?([a-zA-Z0-9_-]{22})$​

(?:invite/)? makes the invite/ block optional.
