Where and how to enable Access-Control-Allow-Origin on opencart 3?

Question

opencart

Good day!
We made subdomains for cities, but when switching to a subdomain, it does not pull up some resources.
For example, font-awesome icons, fonts from the fonts folder, some scripts, etc.
In console it says:
Access to font at 'site_address/catalog/view/theme/default/fonts/ptsansbold-webfont.woff2' from origin ' http://poddomen.site_address ' has been blocked by CORS policy: No 'Access-Control -Allow-Origin' header is present on the requested resource.
And where and how to include this header "Access-Control-Allow-Origin" in Opencart 3?
Everything I found on the net did not work - I added both to htaccess and head - maybe I'm doing it wrong? or I’m putting it in the wrong place, it’s not what you need?))) Tell me
pliz!
