What happens to Chandrayaan-3 propulsion module after lander's separation?

The Indian Space Research Organisation on Thursday revealed the next steps for the Chandrayaan-3 propulsion module, after the landing module Vikram separated from it. It said the propulsion module will continue to orbit Moon for months or even years. It will perform spectroscopic study of the Earth's atmosphere and measure the variations in polarisation from clouds on Earth, ISRO said.
