Knime Pro: Execution credits explanation for billing

Hi friends

I am using Knime Pro on a 60-day trial. This trial allows for 60 days of use and includes 2,000 credits.

My question is the following: When the trial plan ends, I know the plan will cost $21 per month.

My doubt is regarding the credits.

1. Will an additional amount be charged on top of the fee that is already billed? In other words, will the plan always start with 0 credits?, and I will be charged $0.05 per use, or does the $21 fee already guarantee a balance of 100 or 200, or 1000 credits…?
