I have generated an identity in the browser, how can I import this identity into DFX through the pem file for use?

After the .pem file is generated by identity in the browser, can it be imported into dfx for use? Or create a new identity in dfx, how to import it into the browser for use? Is there any way to achieve this? this is important to me.

Keys should not be copied from one device to another. In general, you should instead add other devices’ principals as trusted users to your identities/canisters.

AFAIK, linking a dfx identity to II is not possible as a general authorization. What are you trying to do specifically?
