How do I stream from my iPad to my LG OLED 4K HDR 55B6P TV?

I found a movie I want to watch on https://tubitv.com on my iPad.  TUBITV has "amazing movies and TV shows for free.  No subscription fees, and no credit cards.  Just thousands of hours of streaming video content from studios like Paramount, Lionsgate, MGM and more".

Is it possible to stream the movie from my iPad to my LG OLED 4K HDR 55B6P TV? My iPad is connected to my network using Wi-Fi and my LG OLED TV is connected to my network using an Ethernet connection.

Or, is it possible to stream the movie from my iMAC Computer, connected to my network using an Ethernet connection, located in my office, to my LG OLED TV located in my family room?  Thanks….
