Froala editor colorsHEXInput option

Your software
My Mautic version is: 3
My PHP version is: 7.2

Your problem

I can’t enable the hex color selection for the froala editor.
According to the documentation, it is set to true by default but in mautic the hex color selection is not showing and even if I modify the core to explicitly use:
colorsHEXInput: true

Is there any way to customize the Froala editor that I am not aware of? Or is there anyone that knows why the hex colorpicker is not showing?

When I set colorsText in Mautic.basicFroalaOptions, it is working and change the color selection. But the colorsHEXInput parameter doesn’t work.
