Can I use used programs icons in the "about menu"?

Hello, if in the “about menu” (just part of menu, not a part of gameplay) I put all used programs with their icons, will it be legal? Maybe better to draw these icons badly in Paint? I read that to use Unreal Engine intro I need to ask Epic first, but I not sure about icon.

But who I can ask about this? :smiley: Looks like that Epic have only Premium fee-based support?
