Welcome to stack please read [ask] it is best to explain what it is you are doing first then post your code and describe your issues. Just dumping your code here isnt going to be enough for most people to help you. — Linda Lawton - DaImTo, Oct 24 '22 at 11:14

You have a method called GetClient() which is returning your drive service object. This drive service object is what you use to make all your calls to the api.

Something like this should return you a list of files on your drive account.

var service = GetClient();
var results = service.Files.List().Execute();

Now if you want to only return a specific type of file you would use the search method.

var request = service.Files.List();   // Create file list request.
request.Q = "mimeType= 'video/mp4'";  // List only files of this mimetype
var results = request.Execute();

There are a number of diffrent mine types for videos you will need to check your drive account to see which ones you are looking for.
