Discourse Calendar - How to?

Can anyone share the steps where to find the Postid to declare the calendar? I am stuck at this step and would really appreciate the help.

Edit: found it! In case anyone is struggling, you can take the following steps to find the postId. Let’s take this topic as example:

https://meta.discourse.org/t/discourse-calendar-how-to/165536/5

  1. Remove the slug of the topic so it looks like this: https://meta.discourse.org/t/165536/5
  2. Remove the post number at the end (/5) and replace it with /posts.json, so the URL looks like this;
    https://meta.discourse.org/t/165536/posts.json
  3. Open the URL and you will find the required postId in the first line:
  4. Paste the URL into the calendar plugin settings, so in our example it would look something like this:
  5. Your calendar in the category should now display all [date] entries from that topic.
