Front prop axle boot grease?

Hello everyone!
I replaced the front prop axle boot today (going from the transfer to the front diff), and i was wondering what type of grease is should put there, how much and from were should i apply it.
Right now i just supercleaned the old grease and added new cv joint grease on the splines by hand.
After i was done i was reading the manual and i found out that it says to put Chassis Grease 99000-25030 which i guess i can find at the dealership. Is it that important to put that specifc grease? or should i just let it be with the cv joint grease and it will be fine?

Also i found two different sections that refers on how to lubricate that part and i noticed that one of those, points out the grease nipple which am not sure if its for the splines or the universal joints, which i did not use to put the grease so far. I just filled it by hand and applied grease on the splines and then assemble the whole thing back toghether with propper marks and alignment.
Should i just clean it again, get the propper grease and use a grease gun on the grease nipple to fill it up instead of putting grease by hand from scratch? and if so how much grease should i put? When do i know its enougth?
I think am getting paranoid over small things but i would like to get it done properly since its kinda simple and i have time to do it.
I am adding some pics of the manual and the axle boot to make it clearer what i mean.
First link is the manual and second is the boot on the propshaft i replaced ( pic is before i replace it ) . Is the green arrow in the pic the grease nipple for the splines or for the universal joints??

Thank you so much!

Grease nipple 3 is for the splines. Once you have assembled the sliding joint, add 3 squirts from your grease gun. Don't overfill the unit. The rubber boot must not be full of grease. Also, before you fit the grease gun in place, clean the nipple!

Putting in grease by hand when you assemble it is fine. CV grease or general purpose grease will be fine on the splines. Don't use CV grease on the UJ.

Okay! If i have some time i will redo it to make sure i have the right amount of grease and have the nipple cleaned as well! Thanks for your replies, everyone!
