How can I losslessly concatenate two MP4 files and keep the telemetry info?

[Franck Dernoncourt]

One may losslessly concatenate two MP4 files using FFmpeg as follows:

ffmpeg -safe 0 -f concat -i list.txt -c copy output.mp4

with list.txt:

file 'C:\file1.mp4'
file 'C:\file2.mp4'

However, if the input files C:\file1.mp4 and C:\file2.mp4 have telemetry information, output.mp4 won't have it, as ffprobe can confirm.
