context menu commands are ran as slash commands.

[FisbanRegner]

user context message context and slash commands can have the same command name however your handler does not distinguish between the 3 and always runs the code for the slash command. regardless of the .js files actual name.
example if you have contexttest.js and its registered as type: ApplicationCommandType.message, with a name of test and you have a slashtest.js registered as type type: ApplicationCommandType.ChatInput, when you use the context menu it runs slashtest.js even though contexttest.js was the registered context message command with discord.
