Use the add-signer instruction to add a new signer account to a multi-signer account. the add-signer interface is a multi-signature interface, so the proposal account is created when the interface is invoked.

The new signature is only added when the proposal is called again after the proposal verification has passed.

Query add-singer proposal account information.
