Query about switching from PSW (Graduate visa) to Global Talent Visa

I completed my Masters in Artificial Intelligence with Robotics in September 2021. Currently, I am on a Graduate visa (PSW) and staying in London.

Since I’m on a Graduate visa. Am I eligible to switch to a Global Talent Visa? Or should I leave the country and then apply for a Global Talent Visa from the outside UK?

Note: My visa is not listed under “Switch to Global Talent Visa”

Thank you
