While trying to write a bug report I came across that "share this search" does not work when a lens is active. It will copy a "#" to clipboard and not the link to the search: "https://kagi.com/search?q=aerosol++arctic+willis&l=0"
The link should be copied to clipboard, preferably with the correct lens.
I know that this will not provide the same results for all anyways (since the lenses are indexed and have no uuid) but it should at least copy the search url or disable the sharing feature on lens searches.
