[Python] i want that my scrips in playwright python should get more better cuz they get banned...

I have used this now but for my project but it gets banned in 2 weeks and like browser is get banned only but like i wnat to know that what else can i add to be more non detectable for education and learning purpose , as i am an automation dev,

i am using playwright python and playwirhgt stealth plugin too so assuming all the basics ones that playwrgiht - stealth sync api gives the page non detection spoof is ok but that is so basic , so i added my scripts but i still need refinements, also i know we can change brwoser profiles like rotation with canvas , font , other values to be changed + human behaviour

so here is the code , also if someone can give me detailed list that what else i avtually need to rotate in the values , a list give me plz , and also review this code and suggest me anyting else i can add in this ,
