PHPSpreadsheet - Page layout background

Hi all

We have some advanced requirements for creating Excel files. In Excel, there is a "Background" function (under tab Page Layout) where you can define a worksheet background image. Excel automatically shows the image repeated as a background.

I wasn't able to find any capability in the PHPSpreadsheet package. Does someone have an idea how this can be done through PHPSpreadsheet?

Many thanks for your ideas!
