Which of the following statements about the "first signer" in a PowerForm is true?

The correct understanding of the "first signer" in a PowerForm context is that it must be a placeholder role. This is critical because PowerForms are designed to allow users to initiate a signing ceremony without having a specific person assigned as the first signer. Instead, a placeholder role acts as a variable that can accommodate different signers as needed, depending on who accesses the PowerForm. This flexibility is central to the functionality of PowerForms, as it allows anyone who fits the criteria of that placeholder role to sign without the need for the signer to be predefined in the envelope.

Having a placeholder role makes the process user-friendly and adaptable for various situations, allowing organizations to streamline the signing process without being tied to specific individuals. In a typical workflow without PowerForms, the first signer would often be a predefined user, but the nature of PowerForms is to ensure that it can be accessed by multiple users dynamically.
