How can I create a blurred background for my drawer menu?

Hello, good luck everyone!!

Is there any possibility to make the background of the drawer menu blurred? I’m not talking about a single colour and changing the opacity. I want the part where the menu opens to be a blurred version of the photo on the back. I would appreciate your help, I appreciate it in advance. I send you the link to my page and a sample image of what I want.

Any luck? Trying to do the same. Managed to get it in the header but not the drawer.
