Change track with playerctl + notify !

player_playerctl_next_prev_notify.sh

#!/bin/bash
# DO Change track with playerctl + notify !
# USE Keyboard_media_key => "this_script.sh OPT_1 OPT_2"
# OPT_1 play, playpause, next, previous, infos
# OPT_2 no_notifiy ( disable notif )
# OPT_3/2 target ( app name )
## EX: player_playerctl_next_prev_notify.sh playpause spotify
# FIX If not works => use xtool search app xith its $classname 
# VAR $classname "WebApp-Bandcamp6262" cf. $currentapp
# VAR app classname ... change w/ your need ==> use `wmctrl -lx` to list all
