How to use the @webassemblyjs/leb128.decodeUInt32 function in @webassemblyjs/leb128

function readVaruint7() {
    // where 7 bits = max 1 bytes
    var bytes = readBytes(1);
    var buffer = Buffer.from(bytes);
    return decodeUInt32(buffer);
  }

    const bytes = readBytes(1);
    const buffer = Buffer.from(bytes);

    return decodeUInt32(buffer);
  }
