This is a short and general description of how to interface with a sensor that communicates over serial:

Start by testing the TWI Sensor Example.
Go to Invensense's website and grab whatever C driver they've written for ICM 20648. Almost all serious sensor vendors have built their own generic C drivers, and often accompanying libraries that deal with post-processing of the data.
Exchange the read/write functions in the Invensense driver with appropriate nRF TWI driver calls. See TWIM driver API docs.
