Hi, I checked and it seems you want to send the signing link to the recipient via the WhatsApp and the sender of the WhatsApp message should be from your store's WhatsApp account.
Unfortunately, there's no way to get the signing link other than the embedded signing link. Note that the embedded signing link expires after 5 minutes and is one-time use only, so it isn't recommended to use it in your WhatsApp message, since you don't know when the recipient will sign. More information about the embedded signing is here: https://developers.docusign.com/docs/esign-rest-api/esign101/concepts/embedding/embedded-signing/
Regarding WhatsApp Delivery, your understanding is correct that the WhatsApp message is sent from Docusign and you can't change it to your store's WhatsApp account.
For WhatsApp messages, Docusign has a verified WhatsApp business account. Messages from the account bear a green checkmark next to the name, which indicates it is verified by Meta as a legitimate entity.
If you are okay with the current WhatsApp delivery provided by Docusign, this is the only viable approach for getting the signature from the recipient through WhatsApp.
