Help in Plugin Subscriptions

What is meant by “Plugin Subscription” which is not available in free mode in bubble.io?

Hi there,

When you subscribe to a plugin, that monthly cost is added to your app’s monthly billing. For example, if you were on the $32 Starter Plan, and subscribed to a plugin for $4/ month, you would be billed monthly at $36.

In Bubble.io, a “Plugin Subscription” refers to paid access to advanced features or functionalities of certain plugins that are not available in the free plan. These subscriptions often provide enhanced tools, integrations, or support that go beyond what the free version offers.
