this is how i did it.
1. Download the game/apk file
2. Open APKpure (maybe other related shops/apps works too).
3. Go to the app manager (in the profile or options) and into the "download" tab.
4. The downloaded app should be visible there, find it and just tap/click on it and install it
5. For some reason the app seems to bypass the high file install restriction, if it doesn't start installing it right away tap again till it does
