Since i am a beginner when it comes to things as such, is there any work around to implement your solution ?

Yes, You can actually check my other repo for this implementation.
https://github.com/malik-samad/sequelize-with-typscript
the repo link above contains the initial boilerplate implementation of using typescript with Sequelize. in that repo you will that I have created sequelize models in typescript instead of javascript. and it is working just fine.
(Until my PR is not merged in the Sequelize-CLI repo) you can also use my modified Sequelize-cli package to make it support the typescript
NPM: https://www.npmjs.com/package/sequelize-cli-ts-js
Repo: https://github.com/malik-samad/sequelize-cli-ts-jsI hope this will help in your situation.
@WikiRik any update on ETA to approve the PR? 🙏
check my repos and NPM package for your reference to get you blocker resolved until my PR gets approved and merged.
I don't know how long it may take, maybe it never get merged 😄 seems like the repo is abandoned or something.
the workaround I did is tested and used in production level projects.
@WikiRik any update on ETA to approve the PR? 🙏
There's no ETA. The main devs just don't care.

What I am doing?
I'm using Sequelize-cli in a typescript project and it is not generating .ts files and I have to then update those files extensions and make manual changes to the file for making it compatible in my project.
What I expect to happen?
I want to have the CLI work the same for my typescript file as it does for a javascript project. I expect the cli to generate proper migration, see and model files with .ts extension.
What is actually happening?
When I try to run
sequelize initor other migration cli, it will generate javascript files instead of typescript as expected.Dialect: mysql
Database version: latest
Sequelize CLI version: latest
Sequelize version: latest
