Tomo Fujita Guitar Wisdom

Dear Tomo,
thank you so much for all your Guitar wisdom! I am so happy I found your course I have already improved so much.
I just wanted to ask you, why dont you have more lessons on chords? I mean, a lesson for example where you explain how to create a 7th chord from a standar one. Or the diffrence between Cmaj7 and C7. Or what is acually a chord and how many are there. I have the feeling that, thats the only thing that is missing in your course.

I hope you Can Answer me.
Thank you so so much!

Here is Tomo's comment:

"Thanks so much for subscribing to my Guitar Wisdom. I am constantly making new lesson videos, to help you fill the gaps in your knowledge. In the lessons already posted, I explain all chords by degree. For example, a Maj7 chord = R M3 5 M7 and a Dominant 7th chord = R M3 5 b7."

Dear Tomo,
Thank you for your answer.
Where can I find that video?
