Latest manual/description for 5G SA slices/NSSAI for RM520N-GL?

I am looking for a description of slices/NSSAI for 5G SA.
I want to use a RM520N-GL, if possible.

I think I have an old AT command manual (from 2020?) for RM520N-GL, and there is not much details in…

Do I need a minimal firmware version to use slices/NSSAI without problems?

I think I have

RM520NGLAAR03A03M4G_A0.304.A0.304.zip

as latest firmware (if already installed in module, I must check)

In the thread

there was a screenshot of a Quectel manual (by @Silvia). Would it be possible to get this document?

In RM500Q-AE 5GNSSAI configuration for multiple slices - Technical Subjects / Open Solution - Quectel Forums

there was mentioned a problem, that some parameters cannot be changed if TMSI was already assigned once.

Is this “bug” known or even meanwhile fixed? Or no bug at all? Or is there some description/workaround?

Best regards,

Martin
