How to pass IF statement into SSH in UNIX?

I have the following bash script:

#!/bin/bash

set command "pgrep -x 'gedit' "

ssh -t  [email protected] $command

Now, I want to include this as well in the other device:

if pgrep -x "gedit" > /dev/null
then
    echo "Running"
else
    echo "Not Running"
fi

How can I make the IF Statement run on the other device? I wasn't able to include it in the ssh.

I tried this:

set command "pgrep -x 'gedit' "

ssh -t  [email protected] '

if pgrep -x "gedit" > /dev/null
then
    echo "Running"
else
    echo "Not Running"
fi'

But it didn't work! maybe because there is no command at the beginning?

Thanks.

Invoke bash with heredoc:

ssh -t [email protected] bash <<EOF
if pgrep -x "gedit" > /dev/null
then
    echo "Running"
else
    echo "Not Running"
fi
EOF
