The JAG only applies for CPD points for Train the Trainers (TTT) level courses - not for basic skills, up-skilling, or other level courses. The RCP CPD team only approve courses aimed at post-training physicians, so a course for trainees would not be approved.
However, if you took the course as a post-training physician, then you may consider claiming CPD credits by adding it to your CPD diary as a self-certified activity. The onus is on you to determine whether it is appropriate for CPD or not.
