Error persists even without using http2-express-bridge

What steps will reproduce the bug?

1. Install express and http2-express-bridge dependency with npm
2. Generate ssl key and cert file with openssl directly or using wsl
3. Write index.mjs like

import fs from "fs";
import path from "path";
import http2 from "http2";
import express from "express";
import http2Express from "http2-express-bridge";

const app = http2Express(express);
const tlsOptions = {
    key: fs.readFileSync(path.join("certs", "ssl.key")),
    cert: fs.readFileSync(path.join("certs", "ssl.crt")),
};

app.get("/", function(req, res) {
    res.send("Hello World");
});

const server = http2.createSecureServer(tlsOptions, app);
server.listen(8080, () => { console.log("Server listening on port 8080"); });

4. Add index.mjs as main script in package.json
5. Run with node .
6. Navigate to https://localhost:8080 in browser

Express does not support HTTP/2 (see #5462). The error caused by http2-express-bridge has been reported in the package's repository (rahulramesha/http2-express-bridge#11), but it looks like that project has not been updated in a long time and is abandoned by its author.

I think I found the cause of the error.

The function application.lazyrouter was removed with version 5 which the http2 bridge used to hook prototype overwriting for Http2ServerRequest and -Response on the req and res objects before forwarding them to the router api.

Since the application.router is now not accessible anymore before initialization and prototype overwriting happens in application.handle is there any other way to set Http2ServerRequest and -Response prototypes for req and res objects before application.router.handle is called?
