OAuth Updates for an App for just One Single User (Developer is only user) required ?

I received a mail from Dropbox announcing the Oauth updates by Sept 2021.

I have a very simple Single Page Java Script application - which runs in the browser not in node - and I use the Dropbox-sdk.js.

I am and will be the only user of this application.

It just does a 

var dbxt = new Dropbox.Dropbox({ accessToken: "xxxxxxxxxxx" });

Where xxxxxxxxx is the Generated Access-Token from the App Console.

Then I use the returned object for a download

dbxt.filesDownload({
	path: '/BookLibrary.xml'
})

Thats it.

Do I have to change anything by Sept 2021 due to the changes with OAuth ?
If yes - Could you please provide an example for my simple case.
The "download" example that is provided in the Javascript SDK by today still works with a generated access-token so I guess I don't have to change anything.

 

Many thanks
