Issue to insert plan correctly

[BugKiller-tech]

Hello! Thanks for this good repo.
I cloned this repo and I tried to change plan based on my stripe account.
https://dashboard.stripe.com/test/subscriptions/products, here what I need to copy and paste to the secrets.js
in secrets.js I can see plans and planData variable.
but I don't know what info need to copy for this variables.

there is Product and Product has only one plan, and plan has the info like ID, Created, Nickname, Product.. I can't get make sense what info I need to copy and paste to secrets.js for the plan.

for now, I'm getting error like this.
No such plan: [$PLAN_NAME]

I removed plan lowercase from the code.
