OKR and Slack are completely different things?
Ones a chat app the other is a system of setting objectives and measuring against those objectives.

Does it still make sense when the org is closer together due to slack
Your OKRs put that sort of thing in one place. The process to determine what the OKRs are ensure that everyone's on the same page about the objectives. People in an organization want to feel like they know what they're working towards. When they don't they get stressed out and unproductive.
Most okr are dependent on someone else - the Android app guy will not achieve their okr if the API guy is off doing something else. In that way, the whole aspect of goal setting and achieving that is probably more inefficient using an okr structure than thrashing it out on slack (and most likely in a dedicated channel called "planning")
You need to try and think about what things look like when the company is much, much larger.
If you’re setting them and always missing them because of entities with other objectives, then your organization is obviously misaligned and needs to evaluate its goals.
Slack is a chat app.
You can chat over slack about goals, but slack isn’t goals and goals aren’t a chat app.
You can be on slack or email or around the water-cooler all day long. I don't think that makes that much difference. It's not like as soon as you bring Slack into an organization all this structure emerges that helps you focus your efforts on what to do. Chat app or no chat app, people are always coordinating with each other to complete task-level work.
OKRs help you think first strategically (longer than 1 year) then tactically (between 1 month to 1 year) and then operationally (day to day, week to week). Chat apps don't do that for you.
They just aren't related.
