The README as it is, could do with some restructuring - the main focus at the time was getting the token warning across to ensure consumers of this action did not publish their access token directly onto the repository.

• node:perf_hooks - For accurate timings on operational delay.
• @discordjs/collection - There would be an intention to move to the native Map but that also requires a change in logic to handle sorting roles in their associative positions, filtering for authenticated user roles, reducing filtered roles to calculate permissions and getting the highest role for the authenticated user.
• ms - Handles timing conversion for log purposes.
• node-fetch - Specifically as a 'polyfill' for node16 - will be removed once actions supports node18 by mid-October.
