Plugin or workaround for Continuity Sketch on Mac

What I’m trying to do

I would like to be able to insert small sketches into Obsidian using continuity sketch on a mac.

Is there already some plugin that can do this? Or to at least make this process a bit smoother? e.g., one simple way would be to have a keyboard shortcut that creates a new blank image that then opens in preview.

Things I have tried

A kind of workaround that I have found is that I can take a screenshot of the size of the sketch that I want to insert and then open it in preview, where I can then use continuity sketch on that screenshot. I can then paste that image into obsidian.

But I feel like there should be a much smoother way to do this. It would be great if I could just press a keyboard shortcut and then use my iPad to sketch a quick drawing and when I’m done it just pastes this drawing into Obsidian.
