You also need to login into the game with your account before uploading by pressing the space above the public/unlisted option saying account (or something similar).
In the designer select the three horizontal lines. Then select 'share aircraft'. Take a few screenshots (up to 3). Write a title at the top and a description. There is also an option to make it public (everyone can see it) or unlisted (You are the only one that see it and you need a direct link to access it). You can also edit what it says in the description/title after uploading by pressing the down arrow in your upload and seleting edit
thanks
