Minimal size of the widget

I am using now-playing-widget, that shows me title, artist, and album. I can set max size of it, so that it never went over my other buttons on the touchbar. I have a problem though, because it sometimes shrinks. It is not that title is too short to fill whole length of the widget. It could definitely make the widget bigger and show more information about the song, because it still has some space. I could use some 'set minimal size' to set the size static. Is there anything like this?
Thanks a lot
