How to access result of Trie.get()

[samlinux]

How I can access the result of a Trie.get()

The result is something like ?{name="test"}.

I would like take this result name, store it in a new variable and do something with that.

I facing a Type Error if I would like to access the object property.

Can you create a simple reproduction on the Motoko playground?

Thank you for your response, but at the end I found this solution:

switch(oldNftItem) {
      case (null) {};
      case (?Nft) {
          if (exists) { 
            var _oldNftItem : Nft = Option.get(oldNftItem, Nft);
            var newNftItem : Nft = {
              tokenId = _oldNftItem.tokenId;
              principal = newPrincipal;
              url = _oldNftItem.url;
              creator = _oldNftItem.principal;
            };

            nftBelogsTo := Trie.replace(
              nftBelogsTo,
              key(nftId),
              Nat32.equal,
              ?newNftItem,
            ).0;
          };
      };
