Magnuson MP90 Supercharger rebuild question

I'm rebuilding a Magnuson MP90 Supercharger on a 2009 4.0L Tacoma. I cannot find anything about if the inner/outer bearings in the snout need to be packed with grease prior to installation. If so, what type of grease?
It looks to me that the replacement bearings I received in a rebuild kit from SCOL (Magnuson) are high speed non-sealed bearings that require constant lubrication. Does the oil reservoir in the rear of the snout that provides lubrication to the blower drive gears also supply oil to the inner/outer bearings??

This is my main question - how do the bearings in the supercharger snout get lubrication? It doesn't seem like the supercharger oil readily passes by the blower drive coupler flange through the inner bearing to the outer bearing.

I do not want my fresh blower rebuild to go into self destruct mode due to lack of lubrication.

Any experienced MP90 4.0L supercharger rebuilders out there with answers, I'd love to hear from them.
