not working at all

Still works on my device but sometime the token is expired and need to be refreshed using this steps:

• Open qwen code and authenticate using OAUTH2
• Close the qwen code then execute ccr restart
• Continue using claude code that previously opened with ccr code

any ways to use now ?

how use this?
