window.advChannels = "{{__adv_channels_adapter__}}" Not Working

[smpiondev]

I use window.advChannels = "{{adv_channels_adapter}}"; to distinguish advertising networks, but after building, window.advChannels = "{{adv_channels_adapter}}"; returns "undefined".
My code:
window.advChannels = "{{adv_channels_adapter}}";
console.log("Current ads chanel window.advChannels "+ window.advChannels);
Result: Current ads chanel window.advChannels undefined (IS,Unity,Mintegral)

I tried the below versions but no fix:
1.3.4 to 1.3.9
Cocos Creator: 3.8.2
