Frame Without Rounded Edges

For the project I'm doing, I would really prefer to be able to have an option to just make a regular old text box like in Microsoft Publisher, for instance, where I can adjust the size, shape, outline etc. I effectively need an outlined box of text. I know that you can border texts in Musescore already, but the text border effect doesn't look the best in my opinion. The rounded edges, are very unappealing and it scales weirdly. Is there a way to just have a regular square in musescore, it doesn't even have to be a text box. I just need a square.

Thanks!
