@Daniel Verkman Thanks for asking question!
If you have configured continuous deployment for your Azure Static Web App, then Azure will automatically detect changes to your code in GitHub and deploy the updated code to your web app.
To configure continuous deployment for your Azure Static Web App, you need to connect your GitHub repository to your web app in the Azure portal. Once you have connected your repository, Azure will automatically build and deploy your app every time you push changes to your repository.
If you have already configured continuous deployment for your web app, then you do not need to manually do anything via the portal to update your website. Azure will automatically detect the changes and deploy the updated code.
If you have not yet configured continuous deployment for your web app, you can follow the steps in this tutorial to set it up:

I hope this helps! Let me know.
