How to run moveJ while running moveL?

our research team uses UR10e using RTDE in Python and we are trying to run moveJ and moveL simultaneously.
Do you have any idea we can run both at the same time?

We found a solution in the link below.

It says we need to convert joint rotation to (rx,ry,rz) in the cartesian pose.
But it seems like pose_add and pose_trans are not able to be run in RTDE.
If it is not possible to run pose_trans in RTDE, could you provide a python script for pose_trans?

Thank you in advance.
