Config database size issue

In our organisation we we are using mongodb community version 6. The total storage capacity is 2.6TB. But the config database itself taking more around 600GB. “system.sessions” is taking up that space. The _id index is 400GB which greater than the size of the collection itself. Can I delete “system.sessions”? will it cause any issue?
