How to Pollinate Gongora?

[HumbCa]

Hello, thanks for helping me out.
I have a nice Gongora that has recently opened, I'm trying to hand pollinate it.
I can't seem to find the usual structures for pollination when I compare it to a Cattleya or Oncidium. I'm at complete loss about pollinating this one.
I found the pollen, then found the following diagram, which shows where the pollen is located and all other parts of the Gongora flower:

Then I found the following diagram, which implies there should be a surface similar to a stigma (called "pollinarium") right behind the pollen:

I downloaded and corrected the image:

I can't really find said pollinarium, the flower has a smooth toboggan down to the pollen, this is confusing.
I will appreciate any pointers about pollinating my gongora.
Thanks

I found a lot of links in a search. The pollinia must be removed for at least several hours before the stigma becomes receptive. Then you need to go searching with a magnifying glass.

This is rather interesting, I was unable to find that information, if it isn't much trouble, could you link me somewhere this is mentioned? I find it fascinating
Either way, I will do as you told me right now and report back in a couple hours.

HumbCa -
I discovered that the stigmatic cavity is reached through tiny slits. First, I removed the anther cap. Then I used a tweezers to push the pollinia into the slits. I imagine it would have been easier if I had allowed the pollinia to dry out before attempting pollination.
