How we can add a new skin to a spreadsheet?

I wanted to add a custom skin to the spreadsheet. for example if i want to use material skin. How can do that.

SpreadSheet style was made based on the Flat skin.

There’s no major issues with Webix Material skin, so it’s not hard to customize the existing style of the SpreadSheet.

I know the skins can be updated but i wanted to know how you guys do it. In the tutorial its not there that’s why i’m asking. Could you give me a snippet or something.
