Big potato talk

can someone spoil this for me?

i havent watch BND but I’ve seen some spoilers/short clips about yelena’s talk with Peter saying that the new avengers work on big potato stuff while he works on small potato stuff but Peter has helped the old avengers publicly so many times, yet they don’t remember that?

was she trying to undermine him or something?

or does she not remember when he helped the avengers because he usually had his mask off so they don’t remember it or does his face get replaced with his mask? (i know with normal images he just gets erased completely or something covers his face)
