I am not certain I can offer anything more than the others have said. I am still attempting to avert, rather than redeem, my fate. While I suppose that makes me lucky it also means I am not entirely of use here.
Perhaps just being present - visibly different, from what they remember. That is how I have tried to make things better with these Avengers who knew another me Loki, from another time. It has, thus far, been fairly effective; in your case it may be different, given that you are the one they remember, but the principle may remain the same. You are there. You are different. If they choose to trust you, do nothing to destroy that trust, and whatever you can to continue to earn it back. That is all you really can do.
You seem to be making progress... I am glad to see that.
