Yes, thank you very much for sharing! Otherwise I would not have known about it.

My main argument for building it in would be that some people prefer not to install browser extensions, so having it as part of the website would make this available to those users 🤷‍♂️

Edit: also, some folks use SN on platforms that don't support browser extensions, like on iOS for example. So it would be useful to be built in for that segment.
