How can i screenshare my apple phone with my Samsung TV?

Hey, so im paying for Netflix and Prime Video for movies every month which costs a lot of money over time and i found an website called „Citysonic“ that has every series and movies that i watch for free in HD. I dont know if its called „screensharing“ but basically a year ago when i had an Samsung phone you could display whats on ur phone exactly to TV but now i have an Apple phone so i wanted to ask if i can cancel my memberships and how i can solve this with an Samsung TV
