It depends on which part of the glow effect you want to check. See the API to understand how the function works -
https://www.amxmodx.org/api/fun/get_user_rendering
Bear in mind this function is only available in AMXX 1.9 or above.
PS: there's no point in using "get_user_team" there. Simply add the "e" flag in "get_players" and set it to retrieve only CT players.
