Azure and gzip for js and css bundles

We have those settings in web config, which should be ok for azure to enable compressing.

<urlCompression doStaticCompression="true" doDynamicCompression="true" />
    <httpCompression>
      <dynamicTypes>
        <clear />
        <add enabled="true" mimeType="text/*" />
        <add enabled="true" mimeType="message/*" />
        <add enabled="true" mimeType="application/x-javascript" />
        <add enabled="true" mimeType="application/javascript" />
        <add enabled="true" mimeType="application/json" />
        <add enabled="false" mimeType="*/*" />
        <add enabled="true" mimeType="application/atom+xml" />
        <add enabled="true" mimeType="application/atom+xml;charset=utf-8" />
      </dynamicTypes>
      <staticTypes>
        <clear />
        <add enabled="true" mimeType="text/*" />
        <add enabled="true" mimeType="message/*" />
        <add enabled="true" mimeType="application/javascript" />
        <add enabled="true" mimeType="application/atom+xml" />
        <add enabled="true" mimeType="application/xaml+xml" />
        <add enabled="true" mimeType="application/json" />
        <add enabled="false" mimeType="*/*" />
      </staticTypes>
    </httpCompression>


But when we run pagespeed test, it recommends gzip compression, saying this:

Compressing https://***/…yUOYQY4le8aR_SGYIWj9TWGCZ8hF9H0cPVvJHdQ1 could save 274.8KiB (70% reduction).
Compressing https://***/ could save 195.7KiB (89% reduction).
Compressing https://***/…wqa9wduD7Tw5uVZ4kmI2ngc9RbsGRp39RbX0F901 could save 155.3KiB (82% reduction).


Does anyone know how to enable compression in azure properly?
