When using the sp-textfield, I validate my text on an event. I add the ‘invalid’ attribute which displays the red outline and red error icon. How would I display error text beneath?

My current implementation. I can manually add invalid and show the outline and error icon, but I can’t seem to get the help text → negative slot to work.
