To put it shortly- don’t bother.
The company is shockingly old school, with the management structure painfully outdated. Got ideas how to improve your own work? Too bad, you’re working for ICE.

Lack of career progression and no support from the management or HR, both things that were magnified by the pandemic. Every employee regardless of their work is awfully dispensable.
