LG dryer DLE2516W drum roller leftover part

LG dryer DLE2516W

Rookie mistake! Replaced drum rollers with no issues. All back together and had a leftover part! Small plastic cowl stamped pn 335oel3007. Air duct ? I have watched many utube videos hoping to catch a glimps of where it goes but no luck.

Thanks for your help

That’s a small cover that goes under the top. Here’s a screen snip of the diagram to give some reference, part A560.
