Kinda solved my issue, just reporting in case someone ever had the same problem. Attaching screenshot of CA settings, so that the writing "click here to get more results..." appeared after a "motioneye" search in ca. than I finally found the aart repo/app listed, created a new installation with a different name and port nr, then copied/pasted the config folder from the original motioneye image config using krusader.
Then deleted the original motioneye image.
Sorry, didn't mean to write so much in the tread, hope it can be useful to other al least. Thanks everyone.
ps. aartr/docker-motioneye actually solved the time zone issue thanks
