Arctis Wireless Pro Game Dac Wireless Water Damaged

Hi, Is there a guide on how to open and clean the game dac for arctis wireless pro? I spilled drinking water on mine and right on the side where you insert the battery. So Im pretty sure it got inside and plus it stopped working. I pulled it out immediately and put in rice to dry it atleast.

Any guide here how to open one in case mine does not turn on?
