Setup signature security

When adding a new signer to your signature request, you need to define the security settings for their signature. This is determined by two key parameters:

Signature Level: Specifies the legal and technical requirements for the signature.
Authentication Mode: Establishes how the signer’s identity will be verified.

Choose the Signature Level with the `signature_level` parameter

Choose the security level among the three signature levels:

Signature level	Value
Simple eSignature, useful for online signatures for your daily work	`electronic_signature`
Advanced eSignature, to secure signatures for your sensitive documents (available as an add-on)	`advanced_electronic_signature`
Qualified eSignature, which is the legal equivalent of a handwritten signature (available as an add-on)	`qualified_electronic_signature`

Each signature level provides additional security and legal validity to ensure optimal risk management for all your documents.

Choose the Authentication Mode with the `signature_authentication_mode` parameter

Authentication is an additional step that requires the signer to confirm their identity before being able to sign documents.

Choose the Signer authentication method:

Authentication mode	Value
Without security code (One-Time-Password)	`no_otp`
Security code (One-Time-Password) sent by Email	`otp_email`
Security code (One-Time-Password) sent by SMS	`otp_sms`

The availability of these different modes depends on the Signature Level. For example, the no_otp mode is only available for the Simple eSignature level.
