How to configure npm and package.json in subdirectory Visual Studio 2019 v16.6?

Question

I have a Visual Studio v16.6 .NET Core 3.1 app with an embedded React/Typescript app.

The react app code is located in the /ClientApp folder.
The package.json and node_modules are located within the /ClientApp (root folder).

When this project was in VSC2017, any changes made to the package.json were automatically updated in the node_modules folder.
In VSC2019 when the package.json is in the root folder, the npm dependencies are listed and updated when package.json is updated.

However, in VSC2019, when package.json is located in the /ClientApp folder neither the node_modules nor the npm dependencies are updated.

Question:
Is there a way to configure VSC2019 to look in the /ClientApp folder for package.json and update npm dependencies accordingly?
