Peplink DNS domain policy wildcard not working with ".*"

Hi Team
Trying to apply Domain Lookup Policy in DNS page. But from the description we could use wild card “.*” at the end to match the domain name in the middle.

But after input the wild card it told “Invalid dnsProxy domain name” .


What I input is " googleapis.* "

===================================
You may enter the wild card “." at the end to match the domain name in the middle. If you enter "foobar.”, then “www.foobar.com”, “www.foobar.co.jp”, or “foobar.co.uk” will be matched.
Placing the wild card in any other position is not supported.

Would you please help to check why this happened and how to fix it .

DId someone have similar case before?
Thanks

Any suggestions with this ?
