Chilkat How to start SSH with parameter for Bash Terminal

Question

I am trying to connect to an SSH terminal with the following option.

ssh -t root@IP "bash -l"

I can do it in PuTTy manuall this way:

This is how I am connecting with C#:

sshChannel = sshClient.OpenSessionChannel();

if (sshClient.SendReqPty(sshChannel, "dumb", 1000, 100000, 0, 0))
{

}

I cannot find in the documentation how to do this. Does anyone have an idea? https://www.chilkatsoft.com/refdoc/csSshRef.html
