If you haven't purchased any books on Roll20, then the only content in the compendium is from the free SRD. <a href="https://www.5esrd.com/spellcasting/spell-lists/ranger-spells/" rel="nofollow">https://www.5esrd.com/spellcasting/spell-lists/ranger-spells/</a> As you have done, you can enter anything you want without needing to buy it on Roll20, but if you want content other than the SRD in your compendium, you would have to purchase it for this platform.
