How do I force chord names to top of stave when using multiple voices?

[Marcus Mayo]

Hi all,

I'm using lilypond to practice my voice leading. I want to keep the harmony
as a separate voice for the sake of tidiness. However, when I add a second
voice, the chords appear underneath the staff as opposed to above it. How
do I fix this?

Example:

\version "2.25.11"

\language "english"

<<
\chords {
e1:maj
}

\relative c''
{
\key e \major
e1 |
}
\\
% Chords show above staff until I add second voice, how do I fix?
\relative c'
{
<gs b ds>1 |
}
>>

Thanks in advance!
