How to use the token-types.INT32_BE function in token-types

async function readChunkHeader() {
			return {
				length: await tokenizer.readToken(Token.INT32_BE),
				type: await tokenizer.readToken(new Token.StringType(4, 'binary'))
			};
		}

      count: Token.INT32_BE.get(buf, off + 0),

    };
  }
};
