What case documents do kinship foster parents have a right to in MN (i.e., CHIPS, Case plan, court docs, etc.)

We have had our 2 yr old niece, whom we'd never met, for almost 6 months. We have been estranged from her father for decades and have never met the mother. Long story short, the father (who has not been in a relationship with the mother since shortly after conception, only had supervised visitation and mother had primary custody) has not shown up for the supervised visits for the past 4 months (after a full federal investigation on him was granted) and is MIA as far as the county is concerned. From what the GAL has told us, our niece's neglect is due to BM's severe mental health. Anyway, our niece was just adjudicated a few weeks ago, as the BM was contesting the CHIPS report up until a revised version was recently presented. My question is, what case documents do kinship foster parents have a right to in MN (i.e., CHIPS, Case plan, court docs, etc.) I understand this can vary by state and am having a hard time finding concrete answers online and otherwise. I'm being told by friends experienced with fostering (but not experienced with kinship fostering) that I should have been given the CHIPS report and now a copy of the case plan. The GAL said the case worker is the responsible party. He has been horrible to deal with and says it is not mandatory that he should be giving me that info. If we are to consider permanency - which the CW has asked of us, I believe we have a right to know all the details of this case. We need to be able to have time to come to a decision after knowing all of the facts and what we would be dealing with considering both the BP's know she is with us and would be with us. They are both a nightmare already and we don't even know all of the facts. We have other children to think of as well in regards to what they could potentially be exposed to in the future with these parents. Also, are there differences in kinship fostering vs. fostering as far as legal rights to documents go? Looking for someone here who knows MN laws on this specifically. GAL, extended SW's, and Foster Licensor all do not seem to know for sure. How is that possible? Thanks in advance to anyone with info. I'd really rather not have to pay for legal counsel to get answers.
