Mapping two commands to a key map? (map-bar not supported)

[Grogger]

My goal: Map the key combo <C-w>pp to toggling BOTH the left and right sidebars

To do this in standard vim, we could map two commands using '|', but it needs to be escaped '\|' or replaced with it's code '<bar>'. As mentioned here.

This doesn't seem to work in .obsidian.vimrc:

exmap toggleLeftPane obcommand app:toggle-left-sidebar
exmap toggleRightPane obcommand app:toggle-right-sidebar
"These work
nmap <C-w>ph :toggleLeftPane
nmap <C-w>pl :toggleRightPane

" This DOES NOT work, only the left pane toggles
nmap <C-w>pp :toggleLeftPane \| :toggleRightPane

An alternative would be to make a function, but that doesn't seem supported either (I get an error saying 'Not an editor command: endfunction' ).

Is there a way to do this in .obsidian.vimrc?

Note: I've tried mapping both sidebars in Obsidian to the same key, but that didn't work either. This isn't important, just a little convenience I'm hoping to have.
