Why did Poland dominate the union with Lithuania?

by CrewImaginary9122

I can’t wrap my head over the reason that the crown of Poland, despite being ruled by a LITHUANIAN monarch was still above the Lithuanian Grand Duke status, despite Lithuania being far larger and being the initiator.

Pardon if the question may seem unclear and that I lack knowledge of what should be obvious, but I can’t find sources that explain the union’s…. Policies..

u/Nowa_Korbeja and u/Mixxer5 explain the dual influences of Poland and Lithuania in the Commonwealth here. Especially of interest might be Mixxer’s answer, which talks about why the Lithuanian dynasty did not make the country Lithuanian necessarily.
