Protect Plus UK - Alarm

Hi All, I've been trying to find an existing post to answer this, but haven't found anything that seems to specifically address this. Based in the UK. I've got a doorbell and camera, both on basic plans. Just added an alarm and the obvious choice here is to go for the Protect Plus plan. But when I select to subscribe to the Protect Plus plan, it says it will cover the doorbell and camera but for the "Alarm Base Station" it says "Can't be covered by Protect Plus". It tells me to get Protect Pro, which is not available in the UK. I know the functionality of the alarm in the UK is limited to assisted monitoring and cellular backup for alerting, so does the Protect Plus plan in the UK actually cover this? On the plan features page, when selecting the Protect Plus plan, it mentions nothing related to the alarm, with the only additional features being the extended warranty and 10% off Ring products. Can anyone in the UK who has the alarm setup clarify please? Thanks in advance.
