Registered Trademark in Thumbnail?

Hello,

I hope who finds this is doing well. My apologies if this is in a misleading category. I’m going to be publishing a UEFN project very soon that I’ve been working on for seven months. I own a registered trademark for the title of the map. Given that, in the map’s thumbnail (next to the text), am I allowed to add the “®” symbol for a registered trademark, or would Epic flag this for breaking some kind of rule?

Best, Isaac
