When Sending an Adaptive Card to Teams via MS Graph Can The Copy Link & Title Bar Be Removed?

When using MS Graph and I use the message endpoint to send a message to a channel in MS Teams, and that message includes an adaptive card as an attachment, I always end up with a blank space/padding at the top of the card, and 3-dot menu to the right (with a Copy option).

This padding doesn't seem to appear on any of the examples given in the documentation, and the blank space at the top of all my cards looks a bit naff.

Is there a way to remove this spacing? Or, alternatively, is there a way to add content into this space, and alter the options shown under the 3-dot menu?
