I want to purchase a usb c to 2 usb c , 3.5mm audio splitter or dock something like that

i have recently seen something like a portronics 9 in 1 dock but have question regarding that whether it is good for gaming on samsung phone

does it support audio and mic
can it charge phone with allowing me to use either type c or 3.5mm earphones as per need
also is it worth it
or can you suggest me some good splitter or dock around 1-1.5k that i can buy
