This issue is related with my contributions to a specific project that I have invested quite a bit of time on git.
I have linked my mail on git with my global options and now the commits are recognized. However, what I'm afraid is that I cannot recover my past contributions which are a lot.
I have seen several answers with this related topic but no clear answers of how to assign the past contributions to my account that that did not have a verified mail associated and just a local one for what it seems surname@name-MacBook-Pro.local. Is it possible?
These are two related answers but they didn't help me to solve it (one of them says that is not possible):
