First thing I do at a new job is make friends with IT, if at all possible. I end up being the guy with the new high-dpi screens they're trialling, more RAM in my laptop, and "just DM me in Teams" privileges for tech support. All for not treating these people like tech janitors (and obviously there's nothing wrong with being a janitor).

Cheat code for this: ask them if they need any custom tooling. I spent a few hours at a past job on a userscript for their ticketing interface to fix some annoyances. Brownie points for life.

Depending on where you live, your employer may be legally required to accommodate your disabilities. Here in France, HR are usually dutiful about it.
