Is Figma or Photoshop better for designing mobile apps and handing them off to development?

I'm a UI designer in a large organization. I'm using Figma to design an app and need to hand off the design to the developers, who are used to receiving Photoshop files and do not know Figma. I'm trying to push for Figma but want to know if developers can get what they need to build the app from Figma, or if I absolutely need to transfer everything into Photoshop and hand it off to them that way.
