azureB2C custom policy to salesforce Integration

Question

I am establishing connection between azureB2C and salesforce , i am using custom policy - signupsignin for user login via azure to salesforce.

i am sending JSON response from azure to salesforce like this attached with my redirect uri as query parameters but salesforce is not recognizing state parameter here and throwing error and if i sent response in JWT format salesforce will not accept it , salesforce need JSON response , do we have any option on azure b2c to modify this responseformat :
