Tellraw command with hoverEvent show_achievement 1.14

So, I've been searching the web for a way to get the tellraw command with a hover event of show_achievement. I've tried this command:

/tellraw @p {"text":"Hover","hoverEvent":{"action":"show_achievement","value":"achievement.stoneAge"}}

I'm confused, am I spelling something wrong? Should it be achievement and not advancement? I've tried generators, I've tried help pages, and nothing is working. Please help.

Edit: Is it the achievement. prefix? I am so confused.


show_achievement simply doesn't exist. The only possibilities are show_text, show_item and show_entity. Source: https://minecraft.gamepedia.com/Commands#Raw_JSON_text (archive)
