Helia Example doesn't work

The exercise mentioned to retrieve data from a in browser Helia node, is also useful when you want the in browser Helia node to fetch content from the network. When you manually dial to the browser node from your native IPFS node, and your native IPFS node has that CID then the browser node is able to fetch it.
Still WebRTC is not completed rolled out it seems, and till WebRTC isn’t fully propogated throughout the IPFS network, a helia browser node won’t be able to fetch data from a native IPFS node. Or vice versa.

as @SgtPooki , I am unable to fetch data directly in a Helia node. According to what I observed it seems that fetching data is also not supported properly (I wasn’t able to fetch data in a browser helia node).
