Bp Forums - how to integrate buddypress theme on fully installed bbpress

I'm Back with another question and I hope it's not a stupid one

after installing buddpress and activating the right theme, I wondered how to have forums that look like buddypress.org forums and Not group forums where the forums have the same theme as buddypress theme

we have 2 ways to activate forums through buddpress, either by previously installed bbpress or creating a new one.

I tried both ways, but I end up with either to have group forums which is not what I'm aiming for now, or to have preinstalled bbpress forum which has different theme style

I browsed the buddypress plugin files and I found bb-admin, bb-plugin and all required bbpress file to have standalone version of bbpress.

but when I tried to activate new forums through buddypress panel I didn't see any forums admin panel

I like to have discussion forum for the entire network.

I've read the manuals but nothing helped, Can somebody help me with this please
