Selecting multiple messages in the mail up

Hello all and please stay safe. I want to share a tip I found recently in the mail up. I don’t know if it was available before but I found it under 14.6. When you want to select multiple mail messages together you have to go to edit on the upper corner of the mail up. Then you do double tap on any message and then it says selected so you can’t delete many messages together. I’m not sure if this was available before but I think it’s very handy and it pissed me off before. Anyway hope it helps somebody
