Then how can I call it inside _app.js I tried your solution and called ${process.env.ID} inside _app.js, still undefined

@PujaGarg you can directly use it in the _app.js like "ID".
You can use process.env but for security reasons the vars need to start with NEXT_PUBLIC_ (explained here).
In the .env,
NEXT_PUBLIC_ID=123
In the _app.js (or any front-end code),
process.env.NEXT_PUBLIC_ID

this answer is not correct, because the front-end cannot read envirement constants . this should be read in server and properly in getStaticsProps
