What needs to be added in the google map API referrers if my url is like blob:https://abc.mydomain.com/xyz

I’m using Google Maps in my project. I have the url as blob:https://abc.example.com/xyz
I need to add some restrictions into the google map account. Right now I added
blob:https://xxx.example.com/* as rule, but I am getting Google Maps JavaScript API error:

Google Maps JavaScript API error: RefererNotAllowedMapError
https://developers.google.com/maps/documentation/javascript/error-messages#referer-not-allowed-map-error

I tried to add blob:https://xxx.example.com/* into my google map account, but it didn’t help.

How can I resolve this? Any help will be appreciated.
Thanks.
