What do I do as a hard-breacher after I open the main wall?

For example: On Chalet in snow-mobile garage. After I open garage there’s always 4 people aiming at that angle, I understand as a hard breacher my role is to open up new angles and sight lines on the defenders to make them As pressured and uncomfortable as possible. But do I just sit there till my teammates take map control? I’m confused what to do after this point.

Thanks for your help!!
