Is anyone here using webpack bundler and uploading the zip of dist folder in fb instant app?

Phaser 3
1

I have been using web pack for a year now, I started developing the games for FB Instant SDK recently and I have uploaded the bundled folder which we will get when we bundle using web pack but the pack is not going to standby state instead it is showing Error. I believe it is because of the code of

FBInstant.InitializeAsync().then(()=>{
new Game();
})

is minified and could not figure out by FB instant compiler. any other way to handle this scenario?
