Alternative answers containing comas

I understand that it is possible to add more than one alternative answer, in which case they should be separated by comas. My question is - what if my alternative answer itself contains a coma? How do I do it? Clozemaster thinks they are two alternative answers separated by a coma. Is there any special trick to do it? I tried the {{…}} brackets, just like when adding a new sentence, but it doesn’t work.
