Can someone help me create a test in Postman in order to validate that a key has the expected value inside a nested group?

Can someone point me in the right direction to write a test in Postman in order to validate that a certain key or value from the following response is present. The response has a lot of nested objects. Specifically I want to validate the following:

1. I want to validate that in the output.treatments there's a key "type" with the value "Diet" present
2. and I also want to validate that in the output.treatments.details there's a key "name" with the value "SULFAMETHOXAZOLE/TRIMETHOPRIM"

Or if it's easier, I could also only add a single test that would look for a certain value, in this case "SULFAMETHOXAZOLE/TRIMETHOPRIM" because I don't really care the key that returns it since it's always going to be the same.

Thanks!

The API response looks like this:
