Inputmask.extendDefinitions is not a function when importing via Symfony asset mapper

[dsands]

Using the Symfony asset mapper the dependencies are not being loaded. I think I probably need inputmask.dependencyLib and/or inputmask.extensions.js but I don't see where those are available to install.

https://symfony.com/doc/current/frontend/asset_mapper.html#importing-3rd-party-javascript-packages

Console output:
