How do i publish to gd games

I have exported my game as a link but there is no button to publish it on gd games
I also can’t figure out how to add a thumbnail to my game

if you would like to play my game here is the link

space typing game

Go to the side menu and click icons and thumbnail to select thumbnail

it only opens the icon menu nothing else besides how do you export to GD games?

  1. press the Publish button, 2. Press the generate link button, 3. wait a bit while it loads, 4 then if there is no verify and publish to, repeat steps 1-3, if there is, click it, edit any game info you want to change, then 5. Click Save project and publish
