1. Install this plugin
2. Add the "Sitemap Generator" element to a page.

3. Add the "Create File" action under workflows when a button is clicked to generate the file (see action for more info).

4. Choose the event "Sitemap file was created" under workflows and e.g. download the your new sitemap file.

Tip: You can re-upload this new sitemap file to the root of your Bubble app on the Live version of your app (Settings > SEO/Metatags > Root files). Then update your google search console to index your pages.

Take a look at a demo setup here:
