Help Upgrading my Apps to the Latest Stack version of heroku 22

Job ID: 36348667

Budget: $10 – $30 USD

I need to update my App's to be compatible with heroku 22, currently I have 3 very simple app's that require Upgrading to the Latest Stack version of heroku.
I have no idea how to do it, so I need some help.
I have Visual studio code, with my apps, access to Heroku and I would like it to be done remotely and that I can learn to run this update with a documented step-by-step guide for the rest of my copies of App's.
