Make enter apply the label that is highlighted.

A feature from Gmail that I love is that it's super simple to apply labels with keyboard shortcuts; open label dialog, search for a label and press enter. Job done.

Unless I'm doing it wrong, in Proton Mail on web I have to press "L" to get the labels, search for a label and then use tab key + enter or the mouse pointer to actually apply the label. Instead I want the enter key to apply the highlighted label right away after search (while the search input still has focus) for the right label, without having to do extra keystrokes or use the mouse pointer.
