Hey, this should be the flow that you see when you start your Alby Hub for the first time:

This helps you to get a lightning channel and be able to receive payments. 

DM me your alby account and I make sure that you get a free channel that allows you to receive payments.

the screenshot that you share there is the feature when you want to manually open a channel from some onchain bitcoin. There you need to have at least a certain amount, but higher amounts are better because you want to have big enough channels to send and receive. (the amounts you see there are no fees, but the amount of money that you should have for that feature to make sense)
