Testing bit in extension

My extension is in testing local mode, I added some product and added Twitch.ext.bits.setUseLoopback(true); to reach onTransactionComplete. If I set it to false it doesn’t works asking me to buy bits (actual balance is 0). If setting true I reach onTransactionComplete but domainID, transactionReceipt and transactionID are undefined and userId is always 0.
There is a way to test bit in extension without using setUseLoopback and with balance to 0?

In test mode you need enough bits in your wallet to cover the transaction cost even if bits will not be consumed


I see, so I need to recharge my account only to test it lol. Thx for the info

Yup I got some bits for doing a TwitchRPG survey

So I just hold on to those!
