Bug while developing custom card, maybe someone with experience can help me

[DBuit]

Hello everyone,

Maybe not really the place but don't know where else to reach allot of possible custom card developers.

I have a custom card which makes an dedicated sidebar in hass and it has an option to also generate any card in the sidebar.
This works for most card but for example it does not work for hui-vertical-stack-card this card is not avaialable in the customelements that is the reason it throws an error on setting the config. It does work when i add the hui-vertical-stack-card somewhere in my view because then it loads it in the custom elements.

Someone an idea how i can make sure it is avaiable but more importantly if it is not how can i add it to the customelements?

Thank you for your help!
