Insert keyframe in VSE

[xtech-2020]

Hello, Congratulations, it is an excellent job

Just a doubt, I am trying to generate a macro for a speed ramp in the video editor, the problem is that it does not record the step corresponding to insert the keyframe, I do not know if I'm doing it right, I attach a screenshot.

Unfortunately, the add-on is not able to record keyframes.
I might add it in the future, but that is a bigger task.
