AttributeError: 'Context' object has no attribute 'respond'

Question

I can't send ctx messages as ephemeral it says:

AttributeError: 'Context' object has no attribute 'respond'

await ctx.respond("This is suposed to be ephemeral", ephemeral=True)

So How ctx can be ephemeral ? It only works with interaction ?

EDIT :

tried this

await ctx.reply("This is suposed to be ephemeral", ephemeral=True)
