Accessibility: Button in VPN settings missing an ARIA label (Windows)

Is it a bug?

• I know this is an issue with the app, and contacting Mullvad support is not relevant.

I have checked if others have reported this already

• I have checked the issue tracker to see if others have reported similar issues.

Current Behavior

In the Mullvad VPN Windows desktop app, "> settings > VPN settings", there is a button that is missing an ARIA label that my screen-reader can identify only as "button". It is located in the "custom DNS server" section, and can be found between the two buttons, "add a server" and "more info".

Expected Behavior

Ideally this button should have a ARIA label as well, so my screen-reader (NVDA) can identify its purpose.

Steps to Reproduce

1. Once you have a screen-reader running, (NVDA is free and open source, and available from NV Access):
2. Open the Windows Mullvad VPN application and navigate to "settings > VPN settings".
3. You can quickly navigate through the buttons on the page by pressing 'b'. You will hopefully notice that in-between "add a server" and "more info" is one button that is simply announced as "button".

Failure Logs

Operating system version

Windows 11 25H2.

Mullvad VPN app version

Additional Information

As mentioned above, NVDA screen-reader may be required to identify this bug. It is free and open source and available from the NV Access website. Additionally, this was the only unlabelled button that I personally came across, though there may be others that I am not aware of.
