SSH into Devices running old versions of Dropbear SSH (e.g. UniFi APs, and other routers)

I found this error in the logs:
ERROR 2022-03-24T15:24:37.782 tokio-runtime-worker(ThreadId(3)) [1P:/Users/builder/builds/BhfSvM9x/0/dev/core/core/ssh/op-ssh-agent/src/lib.rs:377] Error handling sign request: Key(signing with ssh-rsa is unsupported; SHA-1 may be insecure)
ERROR 2022-03-24T15:24:37.798 tokio-runtime-worker(ThreadId(7)) [1P:/Users/builder/builds/BhfSvM9x/0/dev/core/core/ssh/op-ssh-agent/src/lib.rs:377] Error handling sign request: Key(signing with ssh-rsa is unsupported; SHA-1 may be insecure)
But when I tried to add these to my config file it got an error:
Host old-host
HostkeyAlgorithms +ssh-rsa
PubkeyAcceptedAlgorithms +ssh-rsa
That and this seems like the op-ssh-agent does not support the legacy key signing.
