Dual SIM feature with handsfree

[Nierewa]

Hi.

Use xiaomi.eu multi V14
Really great work. The Miui camera is so much better than Magisk module for custom ROMs.

But there's a curious phenomenon.

As you know, the Xiaomi Redmi Note 10 has dual SIM.
I have set that the SIM card must be dialed before a call. This also works great,
but not with the handsfree in the car. No chance to select a SIM.
Only SIM card 1 is used.

With a custom ROM (cDroid), the selection was displayed to me with the same handsfree.

Is this a setting thing? How can I get the selection option back?

Thanks
