how to service these grease points. image provided

[Fireblade]

hi
i recently got some swaybar links and they have a grease point ive not seen before.
i thought i could un thread them and put in a m6 grease nipple but these arent even threaded they are a push in fitting.
i pulled one out and its diameter is so small id have to drill out the part and tap it for a m6 grease nipple.

other thought is to pull out the fitting and use a grease needle but i dont think itll work, probably make a mess as the grease wont be forced into the rose joint.

my question is, is there a tool designed to service this style of grease fitting?

I have seen those before but never really thought how to get grease into them.
