Setting up Persistence on a usb

I've flashed a copy of Kali to a USB drive and ended up with 2 partions on the drive

Now does this look right to you as this is the first time i've done this. Oh, and by the way it boots up the Laptop into Kali so it does actually work but the persistent partion doesn't. You can't save anything to Kali's desktop or change any setting on the computer as the next time I boot into Kali its all missing. Now the partion /dev/sdb2 is only 1mb but theres another partion on the drive (54.3GBs) which is unallocated.

Do I resize the 1mb partion to take in the space from the 54.3Gb partion and then create a Persistence partion by clicking EXT4 and naming it Persistence.

I'd be grateful if someone here knows what they are doing can tell me if all this is correct or should I be doing someyhing different.

Thanks a lot.
