ConnectMongoOption field `client` doesn't work with mongoose in TypeScript

• I’m submitting a … [x] bug report [ ] feature request [ ] question about the decisions made in the repository [ ] question about how to use this project

• Summary I have tried to get client connection from opening connection by call mongoose.connection.getClient() to use on client field of ConnectMongoOptions but my vscode give me an error.

import MongoStore from 'connect-mongo';
import mongoose from 'mongoose';

MongoStore.create({
  client: mongoose.connection.getClient(),
  collectionName: 'sessions',
  ttl: 14 * 24 * 60 * 60,
  autoRemove: 'native'
});

• Other information (e.g. detailed explanation, stack traces, related issues, suggestions how to fix, links for us to have context, eg. StackOverflow, personal fork, etc.)

My vscode show this error

Type 'MongoClient' is missing the following properties from type 
'MongoClient': options, serverApi, autoEncrypter, readConcern, and 3 more.

There is a problem with type Promise<MongoClient> for the clientPromise, it is in the same code as example in typescript: https://github.com/jdesboeufs/connect-mongo/blob/master/example/mongoose.js It would be useful to add all examples to typescript, that should prevent these issues. Now here I have to use any to prevent the issue:

  const clientP: any = mongoose.connect(process.env.MONGO_URI, {
      useNewUrlParser: true,
      useUnifiedTopology: true,
  }).then(m => m.connection.getClient());

@mingchuno I’m still seeing this issue with MongoDB set as a peerDep. I removed and reinstalled npm packages too.

"mongoose": "^6.2.3"
"connect-mongo": "^4.6.0"

"mongodb": "^4.4.1"

Any thoughts?
