How to I change from the accrual method to the cash method to report the interest income on my Series EE and Series I bonds?

I previously used the accrual method to report interest income on my past Series EE bonds (which I cashed in a few years ago).  I would like to switch from Method 2 (accrual)  to Method 1 (cash) for the Series I bonds that I purchased in 2022, and would like to know the correct and easiest way to obtain permission from the IRS to do this.  I haven't filed my 2022 tax return yet, and I have looked at Form 3115 and am overwhelmed with the form and not certain how to fill it out properly.  Is there a better way to obtain permission to switch back to the cash method?
