Hiding tab in Vue.js if if-statement is true

I have a Vue component which has a template that goes like this:

<template>
  <div>
    <div class="row" >
      <button class="btn btn-primary" style="margin-bottom:20px" @click="changeSelectedComp">Back</button>
      <button class="btn btn-primary" style="margin-left:1000px" @click="EditMode">Edit</button>
    </div>

    <vue-tabs>
      <v-tab title="Basic">
        <app-players></app-players>
      </v-tab>
      <v-tab title="History">
        <app-histories></app-histories>
      </v-tab>
      <v-tab title="Timetable">
        <app-timetables></app-timetables>
      </v-tab>
      <v-tab title="Scholarship">
        <app-scholarship></app-scholarship>
      </v-tab>
    </vue-tabs>
  </div>
</template>

What I want to achieve is to hide the tabs History, Timetable and Scholarship if this statement is true:

IsCurrentUserMemberOfGroup("Admins", function (isCurrentUserInGroup) {
    if(isCurrentUserInGroup) {
        // hide the tabs
    }
});

This is the IsCurrentUserMemberOfGroup function:

function IsCurrentUserMemberOfGroup(groupName, OnComplete) {

    var currentContext = new SP.ClientContext.get_current();
    var currentWeb = currentContext.get_web();

    var currentUser = currentContext.get_web().get_currentUser();
    currentContext.load(currentUser);

    var allGroups = currentWeb.get_siteGroups();
    currentContext.load(allGroups);

    var group = allGroups.getByName(groupName);
    currentContext.load(group);

    var groupUsers = group.get_users();
    currentContext.load(groupUsers);

    currentContext.executeQueryAsync(OnSuccess,OnFailure);

    function OnSuccess(sender, args) {
        var userInGroup = false;
        var groupUserEnumerator = groupUsers.getEnumerator();
        while (groupUserEnumerator.moveNext()) {
            var groupUser = groupUserEnumerator.get_current();
            if (groupUser.get_id() == currentUser.get_id()) {
                userInGroup = true;
                break;
            }
        }
        OnComplete(userInGroup);
    }

    function OnFailure(sender, args) {
        OnComplete(false);
    }
}

I looked at v-if (Conditional rendering), but haven't understood the syntax. Tried <vue-tabs v-if="IsCurrentMemberofGroup">, but it wouldn't work.

How can I hide the tabs if the if statement is true? (Here's the full component)
