Regaining Access to droplet thorugh SSH, after original ~/.ssh directory is gone

Hey, i can access to my droplet through DO console, in DO/Settings/Security/SSH, there is ssh key with fingerprint, but my original id_rsa files are lost.

Is there a way, that i can get to droplet from my terminal again?

so far i get

code
$ sudo ssh root@167.xx.xxx.xxx
The authenticity of host '167.xx.xxx.xxx (167.xx.xxx.xxx)' can't be established.

ECDSA key fingerprint is SHA256:zxczxczxczxczxczxczxcx
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '167.xx.xxx.xxx' (ECDSA) to the list of known hosts.
root@167.xx.xxx.xxx: Permission denied (publickey).

Thank You
