#Vanilla entity interaction and advancement

I have used fabric api's UseEntityCallback to add an interaction for equipping my mod's item on a happy ghast. Already, this has a problem that is the player sits on the ghast even when I return InteractionResult.FAIL. I also added an advancement for doing exactly this action, but it triggers every time I right click the ghast with the item.

        if (!level.isClientSide && hand == InteractionHand.MAIN_HAND) {
            if (entity is HappyGhast) {
                val handItem = player.getItemInHand(hand)

                val harnessWithPropeller = when(entity.bodyArmorItem.item) {
                    Items.WHITE_HARNESS -> HARNESSES_WITH_PROPELLERS[DyeColor.WHITE]
                    Items.ORANGE_HARNESS -> HARNESSES_WITH_PROPELLERS[DyeColor.ORANGE]
                    Items.MAGENTA_HARNESS -> HARNESSES_WITH_PROPELLERS[DyeColor.MAGENTA]
                    Items.LIGHT_BLUE_HARNESS -> HARNESSES_WITH_PROPELLERS[DyeColor.LIGHT_BLUE]
                    Items.YELLOW_HARNESS -> HARNESSES_WITH_PROPELLERS[DyeColor.YELLOW]
                    Items.LIME_HARNESS -> HARNESSES_WITH_PROPELLERS[DyeColor.LIME]
                    Items.PINK_HARNESS -> HARNESSES_WITH_PROPELLERS[DyeColor.PINK]
                    Items.GRAY_HARNESS -> HARNESSES_WITH_PROPELLERS[DyeColor.GRAY]
                    Items.LIGHT_GRAY_HARNESS -> HARNESSES_WITH_PROPELLERS[DyeColor.LIGHT_GRAY]
                    Items.CYAN_HARNESS -> HARNESSES_WITH_PROPELLERS[DyeColor.CYAN]
                    Items.PURPLE_HARNESS -> HARNESSES_WITH_PROPELLERS[DyeColor.PURPLE]
                    Items.BLUE_HARNESS -> HARNESSES_WITH_PROPELLERS[DyeColor.BLUE]
                    Items.BROWN_HARNESS -> HARNESSES_WITH_PROPELLERS[DyeColor.BROWN]
                    Items.GREEN_HARNESS -> HARNESSES_WITH_PROPELLERS[DyeColor.GREEN]
                    Items.RED_HARNESS -> HARNESSES_WITH_PROPELLERS[DyeColor.RED]
                    else -> null
                }

                if(harnessWithPropeller != null) {
                    entity.bodyArmorItem = harnessWithPropeller.defaultInstance
                    handItem.consume(1, player)
                    return InteractionResult.FAIL
                }
            }
        }

        return InteractionResult.PASS
