How do I remove the black background from png logos

Hi, I am new to blender and unreal engine( I used v4.24). I have exported an fbx file from blender and it works fine on the 3d viewer but when I try to import the fbx file to the unreal engine, the png logos have black background as shown in the image below.

I am actually new to this forum too I dont know what category or tag this is.

Go into your material, made from the png, turn the Material in to “Masked” type. Plug alpha from your color texture into your Opacity Mask. Or if you’re trying to be more optimized Plug alpha into “Dither Temporal AA” node and plug that into the “Opacity Mask” Pin. Sorry if what you see isn’t named exact, I don’t have Unreal open at the moment
