Google Chrome for iOS (well, iPadOS to be precise) will send a web page (not a tab) to desktop Chrome. I know because I do it regularly. The disadvantage of that app is that it lets through most ads blocked by the combination of Safari and the ad blocker Wipr (and I have not bothered to look for an ad blocker that works better with Chrome on iPadOS) with the result that I do most of my iOS browsing in Safari, which means that before I can send a page to my desktop, I usually need to "send" it to the Chrome app, which requires 3 taps, the first of which is a tap on the "share" button near the top right corner of the Safari app. But even with those 3 taps, it ends up being an easier method than the method that begins with my using the same "share" button to mail the page's URL to myself.

I also send pages in the opposite direction.
