Writing

Hello! I've been using musescore from a long time, but I still have some doubts that I don't find a solution for them. I started writing a piece for orchestra, and I added a harp part. The problem is that I have no clue about doing the same as in the image I share below this message, I have no idea about making a group of notes pass through two staves. I will wholeheartedly accept the help.
