Bug: bootstrap5 ESM/ non-jQuery initialization crashes due to Responsive plugin

When imported in an NPM package context as instructed in https://datatables.net/download/npm#ES-module-loader:

import DataTable from 'datatables.net-bs5'
import 'datatables.net-responsive-bs5'

this line https://github.com/DataTables/Responsive/blob/3.0.0/js/responsive.bootstrap5.js#L5 fails due to error:

Uncaught TypeError: dataTables_bootstrap5_default.Responsive is undefined
    mjs responsive.bootstrap5.mjs:13
    __init app.js:38
    js TransactionsTable.js:2
    __init app.js:38
    js index.js:1
    __require app.js:41
    <anonymous> app.js:42837
    <anonymous> app.js:42838

My guess is that this is because here:
https://github.com/DataTables/Responsive/blob/3.0.0/js/dataTables.responsive.js#L1719
Responsive is only added to $.fn.DataTable and $.fn.dataTable, but not to DataTable and that this may work in a global browser window context somehow, but fails when using an ESM bundler.

I have not tested extensively but this issue may also be present for other integrations

Reproduce the NPM ESM setup shown in the issue, starting with responsive.bootstrap5.js around line 5. Then inspect dataTables.responsive.js around line 1719 and compare the exports used by the Bootstrap 5 integration. Done means the non-jQuery Bootstrap 5 ESM initialization no longer throws the reported Responsive error; check whether the same issue affects other integrations.
