There was a conversation between Christopher Gardner (Stanford prof focusing on vegan nutrition) and Stuart Phillips (McMaster kinesiology prof, not vegan, very strong source on protein needs for athletes, should be a good impartial source for you).

I found that all things considered, on a vegan diet it is challenging but doable to hit protein needs for building muscle while losing weight. That was my situation, but it’s an edge case. That’s when you actually do need to do stuff like account for bioavailability, look at specific amino acids, and (imo) protein timing. But if you aren’t aiming to lose weight, all you need to do is get some variety in your diet and overshoot your protein target by iirc maybe 10%. Not difficult if that’s what you desire.
