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 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
