Purpose / Description

• Addresses comment: refactor [squash]: remove CreateCustomStudySessionListener.kt #17510 (comment)

Approach

The comment listed methods which were not actually affected by the PR, but it called out the fact that I was bundling in a separately scoped refactor into a PR

How Has This Been Tested?

⚠️ CI only
