Could I have boba while breast feeding?

Lexie

So I been craving boba throughout my pregnancy and after I’ve givin birth but I been scared to get it Becuase I don’t know if it will make my baby constipated. I usually get a raspberry green tea with tapioca balls it has no caffeine in it just lots of sugar. My concern is . When I eat the tapioca balls will it hurt my baby when I breast feed her ?
