Running an expect script in the background

autossh&.sh

#!/usr/bin/expect -f

set host "host"
set password "password"
 
spawn ssh $host
 
expect {
"(yes/no)?"     {
        send -- "yes\r"
        exp_continue
        }
"*password:*" {
        send -- "$password\r"
        }
}

##Removing this:

##And adding this:
