Front Suspension

Is there anyone here who has a Kaabo Wolf King GT Pro or something like it that has the same kind of front suspension as the wolf king gt pro that knows if they are supposed to have shock oil and if so how much in each tube? I ask because ive seem a couple videos about putting shock oil in and seen a breif discussion on the subject but dont know how true everything is simce there doesnt seem to be any information about it from where i bought the scooter and i couldnt get any info from Kaabousa either, please help
