Can't get to work on Unbounce landing page

I’m trying to create a GTM tag to fire on clicks. However, when I view our landing page in GTM Preview, doesn’t even showing? As this is all newly created, we don’t have Link Click Listener in GTM anymore. What do I need to do to be able to tag clicks on our Unbounce landing page?

@triciaho_melbourne you will have to add a generic link click listener in GTM. Are you saying you added that and it still is not working?
