Survey URL's can be created in many ways (old and new, which makes it a bit confusing when you search for a solution) - could someone please show how it should be done for the latest version of LS.

Survey ID is 999. Group ID 888/question ID 777 needs to be prefilled with the value XXX. Token is ABC123. Passthrough value is YYY. Newtest and language EN should be added too to the URL.

What is the best/most correct way to create the URL, so that everything works?
