reactjs – owl carousel links inside body arent clicking

I’ve created an owl carousel and I wanted to add some external links to my repositories that the user can click.

I cannot seem to click the links inside the body. I have played around with the z-index but still no luck. can anyone take a look at my code and css and let me know if I am missing anything obvious?

  return (
    <div className="projects-container">

        title={"Projects"}
        subHeading={"My Projects I have Worked On"}
