Another low growing trifoliate plant, the common lespedeza (Kummerrowia striata). https://extension.uga.edu/publications/detail.html?number=B1395&title=Lespedeza%20Identification%20and%20Control%20in%20Turfgrass

From this distance and without flowers since there are few plants with similar trifoliate (?)leaves form. I’m unable to go further. For now check out some plants with similar leaves from these included links. If you still don’t know, please resubmit with photos of its stems/ branches, closeup of leaves against a white background (paper, clothe, etc…) and with flowers it would help quickly.
