You will want to configure AGH to forward DNS queries for your local domain to Unbound which you seem to have running on port 5353
based on the "heimdall.blah.duckdns.org" example you provided, do the following
in AGH, Settings > DNS Settings, in the "Upstream DNS Servers" text box add the below at the bottom
#local hosts resolver
[/blah.duckdns.org/]127.0.0.1:5353
This entry will forward all DNS queries for the domain blah.duckdns.org to 127.0.0.1:5353. You may need to adjust blah.duckdns.org and port 5353 based on your actual configuration.
The "configuring upstream" section of the AGH wiki covers this in some detail as well, https://github.com/AdguardTeam/AdGuardHome/wiki/Configuration#upstreams
