yes that's correct, when you customize your own partitions like you have done here you should create a small partition just for efi. So go back and create a partition in a size of 256MB and select efi as mount point.

You can only have one ESP - efi system partition per drive. Best to have all drives as gpt and include the ESP as first partition, even if just data now. Then you can install to that drive later without major restructuring. Ubuntu's installer only wants to install grub to first drive, usually sda or first NVMe drive. Boot-Repair may let you do a full reinstall of grub to sdb. I found work around during install if you do not have sda with ESP. bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1396379
