WordPress | The eventcalendar | modification tribe-events-read-more

I use the “The event calendar” plugin in its free version to generate a music event calendar. All ok with the design, the problem comes with the plugin view format which adds a “Find out more” button:

I want to modify the text of that button, for example, to say “buy tickets” but I have not found any good way. I have verified this guide that is the most approximate, I have replicated it but it seems obsolete since I have no change:

Additionally, when editing the text, I want the link to be a button, which, inspecting the page, takes me to the post:

I want it to redirect to an external page using the event URL of the plugin that has the function “tribe_get_event_website_url”
Is there any functional way to achieve that?
Thanks!
