SharePoint Announcements items' body don't save the complete URL of links

I am working on a Power Automate flow to replace the SharePoint Alert feature (which will be retired in July 2026) to send a notification when new items are added to an Announcements list.

The flow is working fine, but the links I added to the item's body is partial.

The messages sent via Power Automate using Exchange connector replicates this error, so when the recipient receives the message, it looks ok, but the links are broken, because it has only "/sites/finance/home.aspx", not the whole URL (https://company.sharepoint.com/sites/finance/home.aspx).

I'm using the classic interface, and even when I enter the full URL, as soon as I move away from the URL field, it changes to a partial, relative URL (/sites/finance/home.aspx, without the first part "https://company.sharepoint.com/").

Note: when I receive the exact same content via SharePoint Alert feature, the links work perfectly. Somehow, the Alert feature replaces the relative path with the whole URL.

Is there a way to fix this?

Thanks,

Luciano Gomes
