If you're using Tags (multiple childs) in it, you cannot use like:

`WOW, the ${CONFIG.NFT_NAME} is yours! go visit <a href="http://google.com">Google</a> to view it.`

You have to use React.Fragment:

<React.Fragment>
      WOW, the ${CONFIG.NFT_NAME} is yours! go visit <a href="http://google.com">Google</a> to view it.
</React.Fragment>

React.Fragment: A common pattern in React is for a component to return multiple elements. Fragments let you group a list of children without adding extra nodes to the DOM.
