How do I generate the font?

[DusanMilko]

Hello, I see the font comes with an svg folder of all the icons. I have added some custom svgs and would like to generate the font from all these svgs. I've tried icomoon and other services but the result does not match the original font.
What tool do you use to convert all the svgs to the font??

Some kind of build process documentation will be appreciated.
