Was there an official "recission?" Maybe not, but actions speak louder than words. Words said "I concede," but the actions that followed said anything but. Even after Trump was sworn in she continued saying he was illegitimate, as did many Dems and the entire left.
Tell yourself whatever you need to, but an objective viewpoint very clearly exhibits this type of election denial from both sides, setting a precedent for distrust.
Again, only one side is trying to make elections more secure, while the other side fights every effort to ensure only registered citizens vote. Why would anyone oppose that?
BTW Glenn Youngkin in VA issued an executive order that purged 80k dead people and 6,000 non-citizens from Virginia voter rolls. Surely we can agree that's a good thing.
