Finding ImageRectOffSet of spritesheet

So I found this sprite sheet; spritesheet-2 - Roblox and I’m trying to get one of these icons as an image in the game by using ImageRectOffSet, although I don’t know how to find the X,Y of it so it actually shows that one specific icon

I’ve tried a few things but they don’t seem to to work as it doesn’t display that specific icon it just displays some random part of the sprite.

Wondering if anyone would be able to give me a helping hand on how to find the ImageRectOffSet of one of these icons, thanks in advance

I am unfamiliar with that property name but the industry standard is to use a texture and scale the uvs to match the tile then offset the uvs by the size

If it was set up correctly, you can divide the total pixels on an axis by the amount of sprites on the same axis.
