Text on Webpage is visible

I am trying to make sure I have Element Text visible before I move onto the next step on my test. This is what I have tried: Element Text Should Be //<span class="quote__summary__level">public liability only</span> Public Liability Only because the text I want to make sure are visible on the page is Public Liability Only

I have also triend <span class="quote__summary__level">public liability only</span> Public Liability Only

But I am getting this error: InvalidSelectorException: Message: invalid selector: Unable to locate an element with the xpath expression //<span class="quote__summary__level">public liability only</span> because of the following error: SyntaxError: Failed to execute 'evaluate' on 'Document': The string '//<span class="quote__summary__level">public liability only</span>' is not a valid XPath expression.

What am I doing wrong please?

This is the element of the text on the website: <span class="quote__summary__level">public liability only</span>
