Repository structure for HASS.Agent 2.1.0-beta1 is not compliant

I am attempting to install the 2.1.0-beta1 from the Github repository. I am doing so because I don't see the media player entity in HA after installing the original HASS.Agent from the HACS repository.

However, when I try and install the above custom repository I am getting the above HADS error message.

I'm running HACS v2.01 on HA Core 2024.10.2

Help greatly appreciated...
