Have you checked permissions? Since tauri v2, you must provide permissions via capabilities.

In the src-tauri/capabilities/xxx.json:

{
  "$schema": "../gen/schemas/desktop-schema.json",
  "identifier": "application-capability",
  "description": "Capability for the application",
  "windows": ["*"],
  "permissions": ["shell:allow-open"]
}

I double check the permissions .

if you check my demo project the permission is granted but inside an iframe nothing happen
