32:9 resoluton on full screen

Hello! i recently reinstalled overwatch and to my surprise they still dont have a 32:9 resoluton setting (yeah even tho its god damn 2024), is there anyone who was able to fix the problem by stretching the 21:9 resolution to a full screen? i dont care about sensitivity errors and stuff lke that, i just want to play it without black bars.
this video shows what exactly i mean, the guy was able to but even tho i tryed through custom resoluton i still was not able to get there.

the video im talking about is called " Gaming on Samsung’s Odyssey G9 49-inch Gaming Monitor!" by ThinkComputers.

let me know if anyone can help!
