Okay that sounds good but what is that Skill is that the app?

Amazon's Echo Show 8 (3rd Gen. 2023) is compatible with other Amazon Echo devices, including the Echo Dot, but compatibility mainly refers to integration within the Alexa ecosystem rather than a direct physical connection. - You can use the ECHO Show 8 and the ECHO Dot together to control smart home functions, stream music and make video calls, all via the Alexa app and the Alexa assistant. - However, there is no specific physical or wired connection between the Echo Show 8 and the Echo Dot, as they are both separate devices that communicate via Wi-Fi and Bluetooth. So overall, they are compatible in terms of smart home integration and utilising the Alexa ecosystem, but not in a way that requires a direct physical connection.
