Change firebase URL and token

I need to change the URL & token of firebasDB not from the design but from blocks.
how can I do this?

You can do this using firebase extensions:

or use the web component/webviewer to access firebase instead:

i can`t reach to firebase extension by the link that you support it to me.
can you send more specific link to this extension please?

Did you search that page (CTRL+F > firebase) ?
