Who should notify the FDIC about crypto assets?

Could you clarify for me who precisely is responsible for informing the Federal Deposit Insurance Corporation (FDIC) regarding the holdings and management of cryptocurrency assets? Are financial institutions that engage in crypto-related activities, such as custody or trading, obligated to report their crypto holdings to the FDIC? Alternatively, is it the responsibility of individual investors or other stakeholders in the crypto market to make such notifications? Additionally, are there any specific guidelines or regulations outlining the reporting process and requirements?
