How to add mindful minutes to iOS healthkit app in objective C?

I'm tyng to create a simple cordova plugin using objective c.

the purpose of this plugin is to add mindful minutes to the ios healthkit via the app.

Now, I found a few tutorials on how to add mindful minutes to the healthkit ap via Swift like this one: https://www.freecodecamp.org/news/read-write-mindful-minutes-from-healthkit-with-swift-232b65118fe2/

but I need to do this in objective C... However, I cannot find any tutorials on how to do this!

Could someone please advice on this issue of point me in a right direction?

P.S. I'm a beginner in swift and objective c.
