Redeem Minecoins at MCPE?

I would like to buy this:

And I'm not 100% sure how to redeem them but have a guess. I show now how I think how I redeem the Minecoins:

1. Go to the Xbox app and click on "Mirkosoft Store"

2.Click on "Redeem Code"

Enter the code here

I would be glad if someone tells me if that's right. I'm pretty sure it is so just want to "play it safe".

It's right

OK thanks.
