Embryo donation considerations

We are done with our family bit have 3 PGT tested embryos in storage. They've been sitting there for over 3 years and it's now time to do something with them; destroy, donate/adopt or donate to science (if even possible). I have been doing some research on the adoption process and would like to know what I need to consider before making this decision. What did you wish you knew before donation? What are some good resources out there to read, watch, or listen to? I want to make an informed decision as I think this is a very sensitive and life changing decision for my family, the donation family as well as the potential child.
