Hide element based on two values

I have a simple paragraph that I need to hide if two fields have values. Doing with one field is very straight forward but I can’t seem to get the syntax right for two values. Below is my code.

<p class="small text-secondary text-center" dmx-hide="clientdetails.data.query1[0].client_email && clientdetails.data.query1[0].client_key">Client must have an Email Address and Secure Key to access the Client Gateway.</p>
