Implications of unassociating account

[Chump]

I have a temporary issue with not being able to get a hold of the admin that manages my zoom pro account. 

I have an existing scheduled meeting where I need to enable "Language Interpretation" on my account (It's wild that this needs to be enabled at the admin level). 

It seems like my best option may be to un-associate my account temporarily so that I can enable the "Language Interpretation" feature on the account.

1. I want to be 100% sure that if I unassociate my account, that my existing scheduled meeting will still work with my account. 
2. Will I be able to enable "Language Interpretation" on my account, and then add the "Language Interpretation"  feature to the already scheduled meeting, as long as it hasn't started?
3. I'll need a 'pro' account for the "Language Interpretation" feature, will I be able to do a free trial for this having already been on a pro account (but paid under my admin previously?)
4. What are the implications with the payment that's already been made for the Pro account on my admin end?
5. Could I simply reassociate with the account afterwards? 

This is a super convoluted process, because of the way zoom's currently architected. I'm open to other solutions, but this is the best I can think of at the moment and I want to understand all of the implications should I go down this route.
