ssh-agent on bash

[aspacca]

Expected behaviour

when ssh agent is used, one of the keys added to the ssh agent is used

Current behaviour

when ssh agent is used, ~/.ssh/id_rsa is used instead of one the keys added to the agent

To Reproduce

eval (ssh-agent -s)
ssh-add /Users/andrea/.ssh/key_other_than_id_rsa
k3sup install --host=192.168.0.5 --user=andrea
Running: k3sup install
2025/02/20 21:26:31 192.168.0.5
Public IP: 192.168.0.5
Error: unable to load the ssh key with path "/Users/andrea/.ssh/id_rsa": unable to read file: /Users/andrea/.ssh/id_rsa, open /Users/andrea/.ssh/id_rsa: no such file or directory

Additional context

looking at the repo on how the ssh-agent setup works, this should be supported and working on bash, what do I miss? :)
