Does webhooks created with REST API version 1.0 expire after 30 days like v2/v3?

Hi, I’m using the 1.0 version of REST API for webhooks as described here:

It doesn’t mention anything about webhook expiration. However the v2 and v3 REST API docs mention that webhooks expire after 30 days and provide a way to extend them. Does the same expiration mechanism apply to the 1.0 API and if so, how do I keep the webhooks alive?
