How often does the sitemap get updated?

Hello,

We’re absolutely loving this plugin.
However we do have one question: how often does the sitemap get updated?

For example, I added a new blog article yesterday but I can’t see it yet inside the sitemap https://www.levthn.com/post-sitemap.xml

This is the article I’m talking about https://www.levthn.com/blog/colori-e-significati-come-scegliere-la-palette-di-colori-perfetta-per-il-tuo-brand/

The article is indexed so I’m wondering If I have to do something specific to add it to the sitemap.

Thank you in advance for the support!
