The font doesn't change for tutor-mfe using tutor-contrib-branding

I downloaded the tutor-contrib-branding plugin.

Then I added the following to config.yml:

BRANDING_FONTS_URLS:
- https://fonts.google.com/download?family=Roboto%20Flex
BRANDING_FONTS: >-
    @font-face {
        font-family: 'Roboto Flex';
        src: url('RobotoFlex-VF.woff2') format('woff2 supports variations'),
           url('RobotoFlex-VF.woff2') format('woff2-variations');
    }
BRANDING_FONT_FAMILY: Roboto Flex

But the font only changed on pages where MFE is not used. What is the reason?

Hi @estebanetcheverry @Andres.Aulasneo I think your team maintains this plugin? If so, could you provide any assistance here?

Could it be that I also use brand-openedx? openedx/brand-openedx

Also i use tutor-contrib-enable-feature-flag
