Render HTML of embed-deployed Component

I want to integrate my react app to a 3rd party app which enables me to put a script that appends the elements into the html.

But it appears that it is not that straightforward in react. The script does not append the elements so my custom component does not appear on the page.

This is what I am trying to do ( but not a gist ):

function Snippet){
    
    return (
        <Wrapper>
            <h1> Snippet 1</h1>
            <script src="https://gist.github.com/xxxx/e4208e452e32e353b6076944c80a1058.js"></script>
        </Wrapper>
    )
}

Is there a way to do this with just react?
