How does display the validation appearance mark by plugin?

Hello.

I want to display the validation appearance mark (valid, Invalid, unknown) on a signature image by using plugin.

But, my signed signature data is on layer 0 and 2 data. (There is no layer 1 or 3 data.)

Can I set up the Plugin to call the GetAPLabel(), GetLogo() functions to display the verification image?

Or is there another better way?
