.net core response with multiple video files

I'm developing web api with .net core 5.0. I'd like to know how can I response with multiple video files(mp4).
I looked at the links below, but couldn't find a way to response with multiple files.

.NET Core 2.0 Web API for Video Streaming from FileStream
Streaming video files in asp.net core 2

I would like to ask you if the methods below are a way to solve this. If not, please let me know what is the right way.

method 1.

Should I compress multiple files and response it? Then, In front-end side(React js), if I want to show videos in browser, should I unzip file and load it?

method 2.

Should I convert video files to Stream and response it by json? Then, In front-end side(React js), how can I convert Stream to mp4?

Thank you for reading.
