So, we know that there is (or rather "was") the port of QONQR for Windows Phone, now obsolete and pretty much defunct, like OS.
Instead, I would propose to create a port for Huawei phones (mostly P30 and P40) who doesn't support GMS [Google Mobile Services]), and instead have their own HMS (Huawei Mobile Services; mandatory for these phones, optional for others, like my own Mate 9).
Such port would use the HMS Core for functionality, and would be published in Huawei AppStore.
