Difficulty removing spindle

I’ve just built an expedition as a starter kit. It has the Seiko mechanism. I need to alter the second hand but need to remove the spindle again.
The video supplied shows a different lever point that you need to press and I can’t get it back out, no matter how hard I try. I don’t want to break it. Any tips.
Thanks

By spindle do you mean the stem and crown? The video does have a clear indication on where to press on a Seiko movement. You need to push the crown in to its innermost position to see that spot.

Here I copied this from their video. This spot will be hidden inside if the crown is pulled out. So you need to push the crown all the way in.
