Welcome to GF. In my opinion, the best thing you can do is to handle the leo in the way that it is most comfortable. You have found one--cradling it gently. Leos may instinctively regard being held with fingers around them as being caught by a predator. Many will tolerate it but some won't.
I have deleted your other post which was pretty much the same as this post, but in a less appropriate sub-forum.
