this has been rewritten to undefined

When using rollup, a warning is shown:

It leads to https://rollupjs.org/guide/en/#error-this-is-undefined

Is there a way to prevent this error?

No other packages in project produce errors or warnings.

Suggest preventing the error from rollup config side: https://stackoverflow.com/questions/43556940/rollup-js-and-this-keyword-is-equivalent-to-undefined .
Since nice modal uses tsc command to compile the code, suppose it generates some kind of "standard" code.

I saw this solution and would love to use it only if no other choice.

Two places use this in compiled code - __assign and __rest at the top.
I believe this are polyfills to quite popular functions.

Wondering what other libraries do since I haven't seen this warning with other packages and I do think they use this functions 🕵️
