Question about Donor Eggs

I'm very early in the process of learning about the possibility of using donor eggs after a four year failed IVF journey. (I should mention I have bio children). I read another post that referred to a protocol of telling the child they are from a donor egg early on. I could assume the pros and cons of this but would love the perspective (of sharing this info with the child or not) from those who have done it, etc. thank you.
