How much does Gate.io listing cost?

I'm curious to know, could you provide me with an estimated cost of listing a cryptocurrency on Gate.io? I understand that the process may involve various fees and requirements, but I'm looking for a general idea of the financial investment needed to get a project listed on this exchange. Could you elaborate on any factors that might influence the cost, such as the size and popularity of the token, or any additional services offered by Gate.io?
