How do I recover the property list in Libre Office (image)?

On my other laptop, I have clicked away now, unfortunately, I do not remember how I get her out

Far right should be this little gray box with arrow. Click on it.

I miss him…

Second option

"View" menu and click on sidebar that there's a catch in front of it. Then something should be done on the right edge of the picture.

Key F11

Thanks, you saved the evening for me
