Shopify App bridge Session token with php authentication

[eluminous_anis]

Please help me to authenticate Shopify app bridge session token with php shopify library.

https://github.com/Shopify/shopify-php-api/blob/main/docs/getting_started.md

<script src="https://unpkg.com/@shopify/app-bridge@2"></script>

<script src="https://unpkg.com/@shopify/app-bridge-utils@2"></script>

<script>

var shopUrl = 'https://xyz.myshopify.com';

var AppBridge = window['app-bridge'];

var appBrdigeUtils = window['app-bridge-utils'];

var getSessionToken = appBrdigeUtils.getSessionToken;

var createApp = AppBridge.default;

var app = createApp({

apiKey: '123456',

host: 'abcxyz',

forceRedirect: true,

});

document.addEventListener("DOMContentLoaded", async function () {

// Wait for a session token before trying to load an authenticated page

await retrieveToken(window.app);

// Keep retrieving a session token periodically

keepRetrievingToken(window.app);

async function retrieveToken(app) {

window.sessionToken = await getSessionToken(app);

$.ajaxSetup({

headers: {

'Authorization': "Bearer " + window.sessionToken

}

});

}

function keepRetrievingToken(app) {

setInterval(function () {

retrieveToken(app);

}, SESSION_TOKEN_REFRESH_INTERVAL);

}

});

</script>

I added this script but unable to authenticate with php library.
