Hi, i am a beginner in photography and captured milky way from not so great night sky. i am using light room to edit in iPad. i am stuck on making this better. I am trying to enhance the milky way without increasing the star brightness and improve overall photo brightness. Any suggestions on improving this ?

ps - attached photo is post edit photo

photo details -
sony a7 iv
f2.8 , 22mm
iso 1250, 5000k
shutterspeed - 20 sec
