Is there any guide for customizing\extending existing themes of Element Framework - https://ui.refinitiv.com/start/styling ? Or maybe an ETA for the feature mentioned here: https://ui.refinitiv.com/#non-refinitiv-products)?:
Non-Refinitiv Products Themes are designed to be extended, allowing styling changes to fit branding and device specifications. Our next generation of custom theming is in development and will allow on-the-fly changes to component styles. This aligns with the removal of IE support later this year.
Also I am interested in how to properly change a font due to license: https://ui.refinitiv.com/quick-start#font-licensing . I assume that should be a part of a new theme as well.
