Document DB - Enable Performance Insights

Question

Hi

I am following steps mentioned here -https://docs.aws.amazon.com/documentdb/latest/developerguide/performance-insights-enabling.html
to enable performance insights

Documentation mentions that, 
A. Apply immediately - This will also apply any pending maintenance item in queue (If require will also do restart)
B. Apply during the next scheduled maintenance window - your instance ignores this setting and enables Performance Insights immediately

When I try to update through AWS Console and choose option **Apply during the next scheduled maintenance window** (as I don't want to apply any maintenance item in queue) it displays a message the settings that you are trying to change will get into effect during next maintenance window.

Can you let me know if I go with option B (i.e. Apply during the next scheduled maintenance window) will performance insights enabled?

Thanks in Advance

Hello.

I started Document DB with my AWS account and tried it out.  
I have confirmed that Performance Insights is enabled immediately even if you select "Apply during the next scheduled maintenance window".  
As shown in the image below, the status changes to "Configuring-performance-insights" and performance insight activation begins without waiting for the maintenance window.  
The instance status will change to "Available" in about a minute.
