How to send message via vk open api with client js?

Question

API

Connected open api to the page

<script src="https://vk.com/js/api/openapi.js?154" type="text/javascript"></script>
    <script type="text/javascript">
        VK.init({
            apiId: 12345
        });
    </script>

Then I authorize the user
like this

VK.Auth.login(r => {
                if (r.session) {
                    resolve(r);
                } else {
                    reject(r);
                }
            }, 4096);//это маска для получения доступа к сообщениям

Then I try to send a message like this

VK.Api.call('messages.send', {user_id:123, message:"text", v: '5.80'}, function (r) {
                if (r.error)
                {
                    reject(r.error);
                }
                resolve(r);
            });

I get the error
"Access denied: no access to call this method"
Enabling / disabling open api in the settings does not affect the work

Help me figure it out
