A way to use Nik Collection with Apple Photos

I have installed an older version of Nik Collection (pre-DXO) on an iMac running Monterey. I was told I was not entitled to an upgrade or a discount for the new version (totally understandable) but have a question before I purchase the new version.
(1) Does the new version work with Apple Photos - either as an extension or by using the “Edit WIth” command?
(2) I use Pixelmator Pro to do processing that Apple Photos (and some of the extensions I already have) can’t handle. Does Nik work as a plug-in for that or only for Photoshop/Lightroom?
Thanks for any information
