Typically, flows contain several types of blocks, depending on the complexity of the process. Each block contains several connection points. They are marked with gray circles. The blocks in the flow are connected with lines going from one block to another. To connect the blocks, you must click on the starting point (circle) next to which it says "Next Step" and draw a line to the point of the block with which you want to connect the starting block. If you want to connect one of the buttons in the message to another block, you must draw a line from the gray point (circle) to the desired block.
