ADPD188BI can be use for detect just background light/ambient light?

Hello mates,

I am currently using the ADPD188BI to detect smoke on my application, and another requirement for my application is to detect light e.g: the presence of light - no light

I could use an external module/sensor for this task, but it could be cool to reduce cost and extra hardware, use the photodiodes on ADPD188BI to detect it.

what could be recommended a configuration to the registers to just detect background light? I don't need measure the amount of light, just an on/off style
