Hi MagedMoh94 , you can use
if url contains and then fill in
/events/, then you make sure it includes the latest slash. So when going to /events it won't show the button (as it doesn't contain the slash at the end). Going to
/events/something, it has the slash at the end, so then it will be available.
If the events are using a blog-post category, then you are able to only show the button on the post categories selected, this may be another solution too 🙂
