If you wish to use your Raspberry Pi to stream services like Netflix, support for accomplishing this task is now incorporated into Raspberry Pi Operating system.
I have been making the changes described on VPetkov.net site to the Pi native Chromium browser in order to use Britbox Streaming service on a Raspberry Pi. I seem to recall, someone in the E14 community made the recommendation. (Thanks Again.) There is now an official Raspberry Package. I have installed it on a Pi4 with the Raspberry Pi OS with desktop and recommended software release date: January 11th 2021. After completing Britbox service login it works.
I have not tested it with other streaming services but it has been my experience if you can get one service working, the others fall in line.
