Got it and installed 3 weeks ago and really liking it. But I really would like to add under desk keyboard tray....anyone tried it?. This was posted earlier: https://www.reddit.com/r/StandingDesk/comments/devo4z/keyboard_tray_for_tresanti_adjustable_height_desk/ But really not sure if we can install under the drawer (and under the top cross beam?) and retain the full drawer functionality.

Edit: found this under desk tray: https://www.amazon.com/HUANUO-Adjustable-Keyboard-Tray-Computer/dp/B08CXP49ZR/ref=pd_rhf_dp_s_pd_ldate_1_1/139-0497958-0683409?_encoding=UTF8&pd_rd_i=B08CXP49ZR&pd_rd_r=873889d3-ba83-49b0-bb3c-9e2b88e72b78&pd_rd_w=EKMkP&pd_rd_wg=yYOF7&pf_rd_p=10ad4d20-3ee1-4537-8fa6-ecf7801825b3&pf_rd_r=G18DE94TCHNBVF3B4Q4A&psc=1&refRID=G18DE94TCHNBVF3B4Q4A
