Openpose full was not cutting it even it was able to do heart hands duo
I tested openpose full, dw_openpose full and canny. Canny did not yield proper results either since the arm cross did not render most of the time. There are not that many images of this pose online even for reference images so it was a huge struggle.
So that brings us to depth mapping. It finally yielded an acceptable result.

Arms cross heart hands duo

Three individuals performing a united heart hands pose. A legendary technique said to hold power beyond human comprehension.
All three characters must contribute to the same heart for it to be considered a heart hands "trio", either by each forming part of the heart or by overlapping a heart hands over a heart hands duo (post #3369955).
If three characters are forming multiple sets of linked heart hands duos, it's a heart hands duo chain instead.
