📚 Description

Replaces BigInt literal with BigInt constructor function because the BigInt literal syntax doesn’t support being transpiled to browsers that don’t support it, like Safari 12 and 13. Using the BigInt constructor the code transpiles properly, it will just fail if you try to use BigInt in a browser that doesn’t support it.
Resolves #21416
