Creating a new team in a professional plan

My company is currently on Professional Plan. As more people (e.g. marketing, sales, customer service) are joining Figma, we are thinking of creating another team to manage this more effectively.

I see that Professional comes with 1 team.

• What is the cost of adding an additional team?
• Can you transfer existing seats to the new team?
• If I am part of both teams, do I pay for two seats?

Thanks
