Updating meta tags in Adobe Animate CC

Hello guys how ya daing?

in my first experiments with html5 with google swiffy i had to put this tag for the devices not to zoom on things, when clic on device,  wich was

<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0;">

but now i see on latest animate it generates its own meta tag, i try adding the parametters to it but it seems not to work, i also trying to put 2 meta tags but either, so i wonder what is the proper way of dictating this now these days?

now animate adds this tag, and i dont know if they would crash

<meta name="authoring-tool" content="Adobe_Animate_CC">

thank you guys
