Instructions for Reviewers

List of changes in this PR:

• Export button in Bulk Access Management has an extra check in canExport now.
• Tests for the component are modified. This includes tests for the new case and some refactoring to handle the dynamically loaded components.

This can be tested by logging in as Admin and navigating to Bulk Access Management. The button should activate only when there is some selection in both steps.

👍 Thanks @AbhinavS96 ! I was able to reproduce the bug locally, and I've verified this PR fixes it by disabling the "Execute" button until you've completed both sections.
