Since June 20, 2022, the rules for registering tokens have changed: https://github.com/solana-labs/token-list

I have tried the following:

1). Create new tokens through the services:

• Strata Protocol Token Launchpad
• Token Creator Demo

After creating these tokens and attempting to transfer them to another wallet via a web app(web3js), they are defined as NFT:

Also on Solscan, these tokens are displayed as "Unrecognized Token":

2). Then I tried to register the token via Metaplex, but I constantly encountered various errors. My code(JavaScript):

import { createCreateMetadataAccountV2Instruction} from '@metaplex-foundation/mpl-token-metadata';

    const tokenMetadata = {
      name: 'EUR demo-stablecoin',
      symbol: 'EURX',
      uri: {
        name: 'EUR demo-stablecoin',
        symbol: 'EURX',
        description: 'Fully for testing purposes only',
        image: 'https://raw.githubusercontent.com/.../logo.png',
      },
      sellerFeeBasisPoints: 0,
      creators: null,
      collection: null,
      uses: null,
    };

    const createNewTokenTransaction = new solanaWeb3.Transaction().add(
        createCreateMetadataAccountV2Instruction(
          {
            metadata: 'https://vxmxabesb3yfewwf4jcplmstg2fe3cngsphlgnrvwp46iftqdm.arweave.net/.../arweave-metadata-JSON',
            mint: mintKeypair.publicKey,
            mintAuthority: provider.publicKey,
            payer: provider.publicKey,
            updateAuthority: provider.publicKey,
          },
          {
            createMetadataAccountArgsV2:
              {
                data: tokenMetadata,
                isMutable: true,
              },
          },
        ),
      );

   await sendTransaction(
      createNewTokenTransaction,
      connection,
      { signers: [mintKeypair] },
    );

Maybe someone knows how to register a Fungible token in Solana now? It will be especially useful if the example is with the registration of an existing token.
