Hello @thomaso34696569 

try below red text.

var memBuff = new MemoryBuffer();
memBuff.fromString('dummy text');
var textBase64 = memBuff.toBase64();
logInfo(textBase64);

var memBuff2 = new MemoryBuffer();
memBuff2.appendBase64(textBase64);
var text = memBuff2.toString();
logInfo(text);

memBuff.dispose();
memBuff2.dispose();
