Pulling your weight on a team means doing your part even when the part is boring.

Group work splits into visible jobs and dull ones, and the dull ones decide whether the thing works. People who take only the interesting parts are not exactly lazy, they are leaving the unglamorous half to whoever cares most. That person ends up doing two jobs and usually says nothing about it.

Find the boring task nobody has claimed and take it before the next meeting. Formatting, cleaning up, chasing the missing information, doing the count. Claiming that once changes how a group treats you more than any good idea will.
