How to replace a conical "Release from Grid" ray with a Gaussian Beam?

I have a simulation of an off-axis parabolic mirror that colimates a diverging beam from a point source. I have designed. (added below)
At the moment I am doing ray tracing from a "Release from grid" point with a conical shaped ray and a specific cone angle. It works great, but I would like to replace this ray with a gaussian beam. How can I do this in comsol?
I have been looking at the documentation "gaussian beam", but it seems I cannot find a way to get it to work in my comsol... https://doc.comsol.com/6.2/doc/com.comsol.help.roptics/roptics_ug_optics.6.23.html#:~:text=Use%20the%20Gaussian%20Beam%20feature,Value%20of%20Auxiliary%20Dependent%20Variables.&text=Enter%20the%20Beam%20waist%20position,positive%20x%20direction%20in%202D.
