Changing/controlling line spacing within a paragraph

Dear all, I'm new into Rise 360, but am already really frustrated how the text is managed, and more specifically what concerns the interline spacing within a paragraph. I know the topic has already been brought to light in the past, but I was wondering if there is any trick or feature to lower that spacing, to allow more text to be viewed without having to scroll indefinitely on a smartphone, for example. In my case, I'm talking about the spacing symbolized with the red square in the screenshot. For info, I'm using the Google font Work Sans for instance, if that should have any effect on this issue. Cheers
