Where is the 'import from figma' option?

Principle Version: Version 4.7 (4016)

the ‘import from figma’ option is not available at all. All my source files are in figma. Is it possible to use figma (instead of Sketch) in terms of grouping/naming layers in order that the layers are also recognised in principle?

Principle 5 is the version that Figma import got added. You’re not seeing the feature because you’re on version 4.
