Localization using plugin as modal

[zaidas1m]

I am using the @googlproxer/ion-range-calendar package in my Angular project, and I need to configure the calendar to display the names of months and days in a specific locale (e.g., German). However, I couldn't find clear documentation on how to achieve this.

Angular Version: 17.3.0
@googlproxer/ion-range-calendar: 18.0.1

Expected Behavior:
The calendar should:

1. Display month names (e.g., Januar, Februar, etc.) in the desired locale.
2. Display day labels (e.g., Mo, Di, Mi, etc.) in the desired locale.
3. Start the week on Monday as per the locale.

I have set in LOCALE_ID in providers array:

Also, I set calendarMonths:

But result is still months in english:

Questions:
How can I configure the calendar to use a specific locale for months and days?
Is there a specific locale property I need to define, and if so, what structure does it require?
Are there any built-in locales, or do I need to manually provide the localized strings?

Any guidance or examples would be highly appreciated. Thank you!

We use date-fns to handle formatting of date values.
You can change the date-fns locale globally as defined here: https://date-fns.org/v4.1.0/docs/setDefaultOptions
