Connecting with sftp to server who uses legacy ssh-dss (lemm.ee)

I have been trying to connect to a server using sftp from Dolphin. I unfortunately get the following error message:

kex error : no match for method server host key algo: server [ssh-dss], client [ssh-ed25519,ecdsa-sha2-nistp521,ecdsa-sha2-nistp384,ecdsa-sha2-nistp256,sk-ssh-ed25519@openssh.com,sk-ecdsa-sha2-nistp256@openssh.com,rsa-sha2-512,rsa-sha2-256]

The problem might be that the server uses the legacy ssh-dss for connections, which is disabled by openSSH. But while with ssh you may add the flag

-oHostKeyAlgorithms=+ssh-dss

to enable it’s use again, yet I can’t find any option to do the same in Dolphin. Is there any way to do this?

I’m on NixOS 24.05 with KDE Plasma 6.0.0 from the unstable branch.

Maybe you can set it somewhere in Konsole's SSH Config options.
