Mint UI available for Devnet also?

[PolarInu24]

Hey there,

have downloaded this front end mint ui for the latest version of solana candy machine v3, though after updating the env variables as suggested, am only able to run the localhost testing webpage in mainnet. It seems like this is set as a default somewhere in the code.

Have tried to search a number of different terms in vs code to track down anything to do with the network rpc but am unable.

Any assistance with this would be greatly appreciated.

An additional note:
If the guard for 0 sol payment, 0 bot tax, and a defined start time is setup correctly, should the creator wallet be able to mint if intented to be a completely free public mint? Or is it forever restricted as is the creator of the candy machine?

Cheers
