I like the new designs but I do not know how to use them.

Can I get a guide on how to use newly designed chess pieces

I am on a Chrome Laptop

there are 2 ways to use it

1st way: have 18 images of each pieces both in black, white and optionally a background. Then manually import it into the extension on your browser. You can export your design into a .cext file to share it.

2nd way: if you got the chess pieces in 1 file (make sure its a .cext file) then just import the file directly if you scroll down the extension UI

thanks
