Cohere template seems no input for setting system input

[svjack]

Reminder

• I have read the README and searched the existing issues.

Reproduction

_register_template(
    name="cohere",
    format_user=StringFormatter(
        slots=[
            (
                "<|START_OF_TURN_TOKEN|><|USER_TOKEN|>{{content}}<|END_OF_TURN_TOKEN|>"
                "<|START_OF_TURN_TOKEN|><|CHATBOT_TOKEN|>"
            )
        ]
    ),
    format_system=EmptyFormatter(slots=[{"bos_token"}]),
    force_system=True,
)

now cohere seems can not set system prompt

Expected behavior

No response
