I think you might be right, but I give up on trying to link the damn articles.

It’s hard (apparently for me) to find English articles about Chinese etymology. Bunch of pdfs or translations of Chinese pages.

At the latest I saw claims Chinese adopted the “mang” term as late as the 1800’s.

Another said China adopted it at the same time as Portugal, during the 1500s southeast Asia trades.

Their first words referencing the fruit were in the 600’s but that was a completely different word.

I thought this would be an easy find… it’s simultaneously annoying and fascinating how tricky it is to get a clean answer.

Or I’m just dumb. Not claiming my research training is any good, but I Googled my damnedest.
