Get user app metadata in my startup class

How can I do to take all my app_metadata properties in my startup class?
I am setting them, as shown in the picture attached, and I also have a function to attach them in my token(I can see them in my token).
But I don’t know how to do to get them in my local variables from my token.
How can I do that? Is that possible?

Many thanks,
Alexandra!

Hey there @alexandra.damaschin, I apologize for the long delay in response.

We actually have a doc that dives into leveraging your metadata which I have shared below. When you get a chance give it a look if you are still battling this question. However if you have any new questions please let me know and we can dive into those as well, thanks!
