Add a button to a screen

Add a container, and inside that, add a label.
Set the label Text to Default Text. Set container's visible to showClipboard.


Set the button's OnSelect to show the clipboard

Set the Label's OnSelect to do something, and also hide the clipboard.


You could expand on this, and change the container to a gallery and have several default options to choose from that you store in a table or collection.
Good luck with your project!
