WPF text label mouse penetrating-CodePudding

I made a full screen transparent window
Lable is full screen printed text
Lable also can penetrate
But the mouse moved to the text will not be able to penetrate the
How can you make the mouse on the text when also can penetrate

Requirements: some words printed on the full screen, do the mouse full-screen through

Please the great god glad!

You can capture the mouse position on the text, converted to screen coordinates, complete follow-up actions

Need to see the text, I actually do is full screen watermark
