you can use bundle analyzer https://nextjs.org/docs/app/building-your-application/optimizing/bundle-analyzer to detect where is your biggest size packages and try to use something different if possible.
Or instead vercel you can host site on your own where you'll not have this limitations.

biggest file was 25mb, rest was like 500kb

it's not only this size, your main problem is googleapis, it make huge webpack file because it include everything in it, and for some reason unminified here is possible way to reduce it's size https://stackoverflow.com/a/73975868/2590591
25mb is huge
try installing just the google apis you're using
Answer
even if you get the size down to like 20mb, you're going to have a hefty cold-start time for the lambda
(it may even timeout if you're not on the pro plan)

Does this not work with the new "app" version of next.js? It is not working for me. I have a .mjs config file. I don't see anywhere that it shows how to use it for this.

it works a bit different, instead require you need to use import, something like https://github.com/vercel/next.js/discussions/30770
but it works only for client side bundle.
so before it you can just build your nextjs and check built

.next folder with software like SpaceSniffer to check where is most size is occupied, if it in .pack files for server you can open them with vscode and check what they have in it.
