automatic SSH login with ssh key's dont work after sudo

Question

I have an Ansible server with 3 ubuntu servers (hosts). So i want to be able to logon to those servers by typing in the SSH key password once. I have edited my .bashrc with an alias. alias ssha='eval $(ssh-agent) && ssh-add'

Whenever i login to the Ansible server and do:

foulan@ansible-server:~$ ssha
Agent pid 1396
Enter passphrase for /home/foulan/.ssh/id_ed25519:

If i typ in the password for the ssh-key, i'm able to login every server without prompting the password. But if i go after that in root mode by typing sudo su.

And again try to ssh in to one of my servers it asks me for me for the password.

But if i run ps aux | grep ssh

it still shows me that the ssh-agent in the back is running ??

I basically want to be able to ssh to any server in root mode without typing the pass everytime

Any help would be appreciated,

Assign the user with passwordless sudo access. When user is logged-in will just do the following to elevate the privilege:

$ sudo su
