Usage of Sharing button in MIT App Inventor

I want to show the Sharing button which is in the social category on the title label? Can you please guide me how to do it? I want to do it the same as given in the screenshot.
Thanking You,
Yours Faithfully,

You will need to build your own title bar:

Who Needs a Sidebar Anyway ?

Here is the icon

It is possible to add Title Bar icons using the Kodular builder https://www.youtube.com/watch?v=g_F7LAN93Iw but it is not possible to add MENU icons to the Title Bar with App Inventor 2.

Use Tim's work around which hides the actual TitleBar and uses a Label to simulate.

Thanks a lot @SteveJG
