I would like to let you know that that there isn’t a way to link these accounts and I would advise you against adding links to sites that would enable a user to contact you on another website or platform.
Additionally, please make sure to check this help article for more information.
As I could see, no one tell me that I cant' link the screenshot because a competitor's plataform and yes because has contact information there. Maybe is that the explanation of being difficult to understand.

The ideia was exacly that. I don't have any projects here yet, so in my mind show to clients that I have a good reputation in other platafform would help me to give then more safety.
Of all these answers, only you really stop what are you doing to answer me for real.
I really appreciate your attention and humility Mikko, have a great weekend.
