Newbie question

My first post on GitHub ;) I have a game developed in Scratch 3.0 and packaged with Turbowarp, fantastic. What do I need to do to have final score exported from the game, so that I could provide a 3rd party database entry, ie insert name (not username), final score, to have a very basic leaderboard for everyone (not limited to cloud usernames) playing the game out there. Thank you.
