Interaction.type is not reducing type of Interaction

[forest maple]

Having issues with getting the type of an interaction, how can I solve it?

export function interactionIsApplicationCommand<Cached extends CacheType = CacheType> (interaction: Interaction<Cached>): interaction is CommandInteraction<Cached> {
  return interaction.type === InteractionType.ApplicationCommand;
}

gives this error in place of interaction is CommandInteraction<Cached>:

A type predicate's type must be assignable to its parameter's type.
  Type 'CommandInteraction<Cached>' is not assignable to type 'Interaction<Cached>'.
    Type 'CommandInteraction<Cached>' is missing the following properties from type 'UserContextMenuCommandInteraction<Cached>': targetUser, targetMember, targetId, resolveContextMenuOptionsts(2677)
