For Outlook delete all emails of a sender?

I was attacked by Twitch through bots and got 500 followers. Of course, 500 e-mail went hand in hand. Is there a way to delete the mails at once?

I use Outlook over the web and not through the app or program.

You could use a filter to display all emails of a sender, then mark them all and delete them once.

It worked, thanks.
