4231 rcam and lcam problem

Im using 4231 as my main tactic. Played about 700/800 games but i still can’t understand how to play with rcam and lcam. I mean, cam and st are my main attacking roles, rcam and lcam always feel like outside from the action. Maybe because this is not the best tactic for my gameplay...

I like to cross inside but i prefer to attack on the centre. Should i try a different tactic?

If you need to know im a g2/g1 player not elite
