Yes, you need an encrypted (or local) channel to share the Cryptpad URL but this can be achieved by using e.g. PGP or Signal or any other of the encrypted messengers out there. However, being able to send an encrypted message to someone is not the same as being able to collaboratively edit documents in real time (think "Google Docs") with that person. This is where the value-added of Cryptpad lies: Yes, you need to already be able to exchange encrypted messages with your partner, but this will allow you to work on a document together in a secure[1] fashion. For me, this is quite an achievement and not nothing. [1]: "Secure" with all the caveats pointed out in the other comments below, e.g. if you do not self-host but use the cryptpad.fr server you need to trust them not to send malicious JavaScript to your browser.
