Adding SMS authentication for recipients in signature requests.

Sender Instructions:

1. Log in to your Sign.Plus account.
2. Initiate a signature request by uploading the document that requires signatures. After uploading, navigate to the Add Recipients section.
3. Enter the email addresses of the individuals who need to sign the document. Ensure each is listed correctly to maintain document security and order.
4. For additional security, enforce SMS verification for signers: Find the recipient’s role (default set to Needs to Sign) and click the shield icon (highlighted as [1] in the image) beside it to access Recipient Verification options.
5. Select SMS from the drop-down menu (indicated by [2] in the image). In the newly appeared text field (marked as [3] in the image), enter the mobile number of the recipient. This step ensures that only the designated recipients can access and sign the document using a unique SMS verification code sent to their phone.
