Steam and Minecraft

I had already pre-ordered the deluxe pack of minecraft dungeons 2, but after release i noticed that steam also offers minecraft dungeons 2 with even the exact same screenshots as the minecraft.net has. But I noticed that I would still have to spend another $50 to get it on steam whilst i already have it on the most correct and true area/the minecraft.net store. So the suggestion is, to allow people to launch it via apps which are all on the same device as the device it was purchased on/something allong those lines. Or make it that its “free” on steam, but u have to login using microsoft or something meaning u have to have bought dungeons 2 via the minecraft.net since else it notices that you shouldnt be allowed to play dungeons 2 via steam since u dont have the game, meaning making steam more like of a extra running option which still would require the game to be bought via minecraft.net. Cause next to that, im like getting confused about the differences or changes or problems that could appear when buying it from steam and getting the refund from minecraft, or keeping it bought via minecraft.net and yet missing stuff that steam would offer…
