patch https://ironcladapp.com/public/api/v1/workflows//sign-status/signers/
Reassign a signer or edit an external signer's name or email, as specified by the signerRoleName
parameter. The original signer will receive an email that the packet has been reassigned if it was sent out for signature.
OAuth Scope required: public.workflows.updateSigners
NOTE: Editing a signer will not cancel a signature request unless your configured signature provider is Adobe Sign. Also, you cannot update a signer that has already signed via the API for any signature provider.
