I actually might have found the solution as I was searching. Solution would be coming from https://www.technipages.com/chrome-enabledisable-not-secure-warning if you want to see it yourself. Otherwise, steps listed below:
-
Go to
brave://flags -
Search
Insecure -
Enable
Insecure origins treated as secure
NOTE
It shows as if you can put in the custom websites you want for it. It doesn’t seem to work on a global scale, if I’m seeing it right. If you want to go that step further, you may want to tag Mattches in and see if he can answer. But at least think I might have been able to get you this far. Hopefully at least solves it for your site if you do that.
