Using ampli-panel-card plugin - help needed on advanced functions

Hello, I have a Onkyo receiver using the built in HA support and the ampli-panel-card on a dashboard. The basics such as power on/off , volume and input selectors are visible and work. However, if I select for example the FM tuner there is no option to change channels or search. Selecting Network source goes to the last used stream but no option to change/pick source.
In the demo video , I see that those type of conditional prompts/controls are possible. I can’t seem to find any examples or clues what type of configuration detail is needed to implement this additional control in this panel.
I am using the latest version of HA and the plugin. I have both Onkyo TX-8050 and TX-NR929 receivers I am wanting to configure.
thanks for any assist
