Please Allow CMYK as a Color Option

I've recently discovered Adobe Express, and it has been a total game changer when it comes to social media content creation. The UI is user friendly, it has a lot of useful features to create more engaging posts, and the integration across all Adobe software makes my life so much easier. However, there is one glaring issue that I have been struggling with, and that's the fact that Express only uses sRGB. I work with a lot of licensed brands, and I need to use their brand colors to keep consistency. Express has made this fustratingly impossible. The vast majority of assets from these licensors are coded in CMYK, and no matter how many ways I try it (such as adding the logos and assets to my library, changing the color profiles in the document, exporting as a png, etc.) I always get a color mismatch, usually resulting in a duller and darker color than what was intended. I'll double, even triple check that is has the right hex value, RGB numbers, CMYK percentages, you name it, and the color always appears wrong when importing those assets in Express. I am the furthest thing from a design expert, in fact I gravitated towards Adobe Express because it is so rookie friendly, so if anyone who actually knows their stuff can point me in the right direction on how to solve this issue, please do. Otherwise, I assume adding a CMYK color option in Express is the only solution. Which, if that's the case, I think that would be super beneficial to more people, as I am willing to bet as most people who are using this software who are like me have no idea what is happening with the color of their imported assets.
