}

ipfsGatewayTools.convertToDesiredGateway(sourceUrl, desiredGatewayPrefix)

const desiredGatewayPrefix = "https://mygateway.mypinata.cloud";
const convertedGatewayUrl = ipfsGatewayTools.convertToDesiredGateway(
  sourceUrl,
  desiredGatewayPrefix
);

//In the example above, the resulting value for convertedGatewayUrl would be: https://mygateway.mypinata.cloud/ipfs/bafybeifx7yeb55armcsxwwitkymga5xf53dxiarykms3ygqic223w5sk3m
