Esignature Configuration Policy?

Hello everyone, 

do you have any idea, what Esignature Configuration Policy is? 
According to the documentation it should be available starting with R2023x FD01 (onCloud and also onPrem):
where can we find a list with the supported apps? 

(Online docu -> https://help.3ds.com/2023x/english/dsdoc/SharedUserMap/esign-m-sb.htm?contextscope=cloud&id=86df28a251b3408f980047345cd33e43 )

Thanks! 

Best regards, 

Radu
