Click on web component

I'm trying to create a webapp and the web page has some buttons that download or visualize a file.
These buttons works on browsers like Chrome, Edge, ecc...
How can I make the buttons work?

See here for some blocks ideas:

or read all the custom webview documentation. It is in there too.

These buttons are links or a javascript that normaly open a new tab in the browser and trigger a visualization or a download of a file (tipically PDF).
How can I visualize these new tabs?
