Anyone using Nigeria FIRS Automated Tax Remittance System?

One small youth owned business in Nigeria was approached by FIRS to start using the FIRS Automated Tax Remittance System as explained at https://atrs.firs.gov.ng/index.php and linked from the https://www.firs.gov.ng/vat-automation-programme/ .

We would like to know if anyone on this forum has experience with this new system and managed to have Manager comply with it. The relevant technical API docs are at https://atrs.firs.gov.ng/docs/ and they seem not to deviate much from other countries.
