Use a Different Note!
Say you are joining in with your left hand playing the chords… alternating bass and chord e.g. G bass, G major, G bass, G major etc. I call this “Root, Chord, Root, Chord”. The next step might be to play: root, chord, 5th, chord. The 5th is D bass which is next door to G bass so it’s not too tricky. In fact the whole G scale in bass notes is only a button or two away so try different ones! Here are some of my favourite moves:

Root, chord, 3rd, chord. The 3rd is always the note on the counter bass row next to the root.

Root, chord, 6th, 5th.

Root, chord, 7th, chord, 6th, chord, 5th, chord.

Root, chord, 5th, b7th. (For modal or minor stuff)
