V-slot: how to skip first element?

Question

Vue.js

Hello everyone, I use slots when building a tree (the "template" object will be added dynamically and as much as necessary), the framework is vuetify and the component for building a tree is v-treeview.
The problem is that the slot adds buttons (underlined in the screenshot) to the folder in which the templates are located and these buttons are not needed on the folder itself. How to remove them?

<template v-slot:append="{ TreeViewTemplates } ">
            <v-btn small> <v-icon>mdi-plus-box</v-icon> </v-btn>
            <v-btn small><v-icon>mdi-file-edit-outline</v-icon></v-btn>
            <v-btn small v-show="false"><v-icon>mdi-content-save-settings</v-icon></v-btn>
            <v-btn small> <v-icon>mdi-minus-circle-outline</v-icon></v-btn>
          </template>

TreeViewTemplates: [
       {
        name: "Шаблоны",
        children: [
          {
            name: "Шаблон-1",
            file: "template",
          },
          {
            name: "Шаблон-2",
            file: "template",
          },
        ],
      },
    ],

buttons on the folder itself are not needed

Treeview slots have a parameter indicating whether the current treeview element is a leaf (i.e., does not contain child elements). Use its value to conditionally render slot content:

<template #append="{ leaf }">
  <template v-if="leaf">
    <v-btn small><v-icon>mdi-plus-box</v-icon></v-btn>
    <v-btn small><v-icon>mdi-file-edit-outline</v-icon></v-btn>
    <v-btn small><v-icon>mdi-content-save-settings</v-icon></v-btn>
    <v-btn small><v-icon>mdi-minus-circle-outline</v-icon></v-btn>
  </template>
</template>
