EU commissioners are not, in fact, voted in by party blocs in the EU parliament - they're picked by the President of the EU, who is selected by an opaque and dubious process behind closed doors. The description of it in the comment chain you're replying to is about right. In fact the winning party bloc in the EU parliament backed someone completely different as President and kinda ran for office on that basis but that didn't matter and van der Leyen got the job despite not being the chosen candidate of any party bloc, with the parliament merely reduced to rubber-stamping that decision.

People get confused about this because her predecessor Juncker supposedly got the job for this reason; in reality this was a ploy by well-connected EU insiders to make Juncker specifically President, and this rule has not been applied previously or since and likely wouldn't have been if some other party bloc backing some other candidate won instead.
