Bigger font CSS code for multistream chat

So I am just beginning to use restream and botrix to stream to both kick and twitch for free. However the only issue I'm running into is that my chat is WAY to small. The space for my chat is small to begin with but it was working fine when I was streaming to just Twitch alone and I used streamelements. I could manipulate the size and all that just fine and it looked great! Right now the biggest size for Botrix is 32 px. I can't go any higher. I have to make the 'box" pretty small and I feel that affects it but I don't want the text to go outside of the designated area and look bad. I don't know what to do other than use CSS to fix it, but I can't find anything on it and I don't know code at all. Can someone help me please?

I took a screenshot of my OBS as well because I'm not sure if I'm explaining well and don't want to make it unnecessarily hard, thank you so much in advance!

That is how small the text is currently
