I have imported the pega provided DX component and added the ruleset ConstellationUIGalleryLib to the application stack if i want to use anyone of the component from the list how i can i add it to the view. For ex: i want to configure actionable button on click of it i need to launch a modal dialog (flow action) and i can perform something.
Refer the below docs to first enable the component in your application.
Then, go to a view, follow the steps in below link. You need to add the key property of your object to the view and then update its config.
