Some infromation you might want to mention with the HUD widget action.

ReachVariantEditor/native/src/ReachVariantTool/game_variants/components/megalo/actions.cpp

Line 483 in f8d3038

"Modifies the text for a HUD widget. You can stitch values together dynamically.",

If you attempt to display a player name in a hud widget the player variable network state must be High Priority or non-hosts cannot see the player name. I believe this applies to player names in waypoints also but I have not tested that.
