Ember has-block to detect empty block

In ember octane, is there a way to detect is not an empty string?

The has-block function will return true if we use an empty component like this <IntakeFormElement></IntakeFormElement> while false when <IntakeFormElement/>.

How do I get both <IntakeFormElement></IntakeFormElement> and <IntakeFormElement/> return false?
