Retrieve config data by decoding Certifcate Signing Request (CSR)

Question

I have CSR with me provided by an authority. I like to generate the config data from that CSR. I already build some config.cnf and tried creating the CSR, but when verifying with the authorised platform it's not working. I believe there is some missing values in my config.cnf, hence I want to obtain config data from provided CSR. Authorities doesn't provide any config content, hence the problem. How can I obtain full data of config.cnf from CSR.

I tried decoding CSR with online decoders, but cannot understand the data properly. I don't have any knowledge on this. This is for Zatca E-Invoice generation which is to be used in Saudi Arabia for business.

The CSR provided by Zatca is below:

The config data I built is below:

I created CSR with above config.cnf but it's not accepting in Zatca QR verification. Actually the config data is correct but for E-Invoice QR verification it's not accepting. Only above mentioned CSR is ok.

So I would like to get all data they used in config for creating that CSR. I have tried everything possible, but because of less knowledge I failed. I have been working on this for one week.
