You can merge scripts and allow tray to close itself after some time.

#!/bin/bash
u=$(xprop -name "Polybar tray window" _NET_WM_PID | grep -o '[[:digit:]]*')
if [ $u -Z ]
    then polybar hiddentray &
        sleep 10
        u=$(xprop -name "Polybar tray window" _NET_WM_PID | grep -o '[[:digit:]]*')
    else kill $u
fi

forget to add kill$u after i defined it in then

Fixed:

#!/bin/bash
u=$(xprop -name "Polybar tray window" _NET_WM_PID | awk -F "= " '{print $2}')
if [ $u -Z ] 
then polybar tray &
sleep 10
u=$(xprop -name "Polybar tray window" _NET_WM_PID | awk -F "= " '{print $2}')
else kill $u
fi

MAKE SURE TO CHANGE tray on the then polybar tray line to the name of your bar that is showing up.

"Allow tray to close itself after some time". Not good idea @k1ake, I open tiiny bar and this bar stays opened till I manualy close it. Because I need that, for see a weather, and networks statistics.
