GetBank() method

I.m having issues with getting the pointer to an already loaded bank. I’m using GetBank() method but it always returns error FMOD_ERR_EVENT_NOTFOUND, and nullptr. But when I use the same path variable to loadBankFile() it loads bank and return FMOD_OK. So can you please help me to overcome this issue. What format of the path do I need to send to GetBank() method?
NOTICE: I’m using UE4 plugin version 2.00.05 and UE4 4.22.3

path may be a path, such as bank:/Weapons or an ID string such as {793cddb6-7fa1-4e06-b805-4c74c0fd625b} .
