What is the .ssh/config corresponding option for ssh -N

Question

I am trying to set up an alias in my config that should give the same result as

ssh -N -L 3307:1.1.1.1:3306 username@remoteip

My current .ssh/config looks something like this.

Host connect
    User username
    HostName remoteip
    port 22
    LocalForward 3307 1.1.1.1:3306

What do I put in the above config to not start a shell?

Host connect
    User username
    HostName remoteip
    port 22
    LocalForward 3307 1.1.1.1:3306
    SessionType none

sessiontype just gives Bad configuration option: sessiontype even though its documented on manual for ssh options

What version of SSH are you using (ssh -V)?

From the release notes it looks like this feature was only added in version 8.7 released in August last year. Maybe updating SSH might solve your problem?
