Missing supporting files for new .ino

[appoli13]

Apologies if you just haven’t had a chance to get to this yet, it has only been 10 days since you published the new file:

I tried flashing my M5Stack device & got an error that a supporting doc was missing (arduino_json.h I believe). As usual Arduino IDE highlighted the relevant part of the code and it seems like there are some other files that are missing as well.

Thanks for all the help!
I would just go ahead and use the older version, but after spending ages fixing various formatting issues (primarily code in Unicode/html format) I got to an error where I can’t tell what is wrong so I’ve given up on that for now…
