It's a conundrum. Most (certainly not all) activists, particularly white political activists, are economically comfortable, so their economic protests aren't as urgent, whereas POC who are protesting racial injustice are understandably more urgent, so the notion of a comfortable white activist convincing a POC that economic activism is equally as important as racial activism is a difficult sell. I've noticed that economic focused activist POC, such as Briahna Joy Gray, tend to be treated like tokens and Uncle Toms by racially focused activists.
I wish I saw a way to circle that square, but I don't. It seems that socialists finding legitimacy with racially focused activists, or vice versa, requires making political concessions that undermine their philosophy. Included in that concession, for socialists, is a burning resentment of poor whites that almost requires political abandonment.
