How to hide a bootstrap-vue modal after clicking a button in laravel vuejs

I am new to laravel and vue.js.

In a blade view, I have a bootstrap-vue modal which includes a vue.js component for a full-text search and sends a post request to the backend when clicking a button.

So I want to hide this modal after clicking the same button after performing the request.

I have tried to access modal using ref attribute and then call the hide() method as stated in the documentation here, but it doesn't work, I don't know what I am missing.

Here is my code:

index.blade.php:

@extends('layouts.app', ['navId' => 'teams'])
@section('title', 'Teams')
@section('content')
    <div class="container-fluid mt-5 pt-5 col-10">
        <div class="row">
            <div class="col-3 offset-6">
                <b-button v-b-modal="'myModal'">Add Users</b-button>
                <!-- The modal -->
                <b-modal id="myModal" class="" size="s" centered :hide-footer="true" :hide-header="true">
                    <div class="row justify-content-center">
                        <h4 class="">Add new Participant</h4>
                    </div>
                    <user-search />
                </b-modal>
            </div>
        </div>
    </div>

@endsection

UserSearch.vue:

<template>
    <div class="" ref="myModalRef">
        <div class="card">
            <input type="text" placeholder="Search ..." v-model="keywords" v-on:keyup="autoComplete" 
                    class="form-control bg-light border-0">
            <div class="panel-footer mt-2" v-if="results.length">
                <ul class="list-unstyled">
                    <div class="result-item my-3">
                        <li class="media mx-2 my-3" v-for="result in results" :key="result.id" @mouseover="hover = true"
                                                        @mouseleave="hover = false"
                                                        :class="{ active: hover }">
                            <img :src="result.avatar_path ? result.avatar_path : '/img/dashboard/user-placeholder.png'" 
                                    class="rounded-circle align-self-center mr-3" width="40" height="40"/>
                            <h5 v-text="result.name" class="mt-3"></h5>
                            <div class="media-body d-flex justify-content-end mt-3">
