Undefined member's banner and accent_color

[MineOnlyDiamonds]

Hi, I'm making a discord bot and currently, I'm working on rank cards. I want to set the background of the rank cards to the user's guild banner - member's banner or to user's guild accent_color - member's accent_color. I'm trying to get it via
"https://discord.com/api/v10/guilds/${guild.id}/members/${userId}"
and it couldn't find anything. I printed it and there isn't a member's banner or accent_color defined only a user's banner and user's accent_color.

There isn't a defined banner or accent_color for members, only for users.

And Discord API Documentation already has it written (banner)

Sorry, if I've made mistake in grammar.

bots can't access per-server member banners, there's already a feature request for that at #4217

But Discord API already has it written.
