*** Variable ***
${base_url}    https://api.sportpartnerxxx.vn/v1

    ${body}=    Create Dictionary    client_id=sportpartner-mobile-app    client_secret=ifd-sportpartner-secret-2021-mobile-app    grant_type=password    username=abc    password=123456
    ${header}=    create dictionary  content_type=application/x-www-form-urlencoded
    ${response}=    Post    ${identity_URL}/connect/token    headers=${header}    data=${body}
    ${token}=    Set Variable    Bearer ${response.json()["access_token"]}
    Status Should Be    200


Refresh token
    ${body}=    Create Dictionary    client_id=sportpartner-mobile-app    client_secret=ifd-sportpartner-secret-2021-mobile-app    grant_type=password    refresh_token=${refresh_token}

Variable crated in a case is local (visible) only in it, and in the keywords it calls; once the case ends, the var is deleted.
If you want it to be accessible in a follow up case, you need to extend its scope - call Set Suite Variable with it, or Set Global Variable - which will make it available for any other suites ran after this one.

This has one big drawback, though - you're adding dependency on the cases order; "Login" has always to be ran fist - and to succeed, so that "Refresh token" works.
That's why this is usually done through keywords (called in case setup, etc).

I'd kindly suggest to read about variables scopes in the user guide - http://robotframework.org/robotframework/latest/RobotFrameworkUserGuide.html#using-set-test-suite-global-variable-keywords

You could try saving the variable with
Set Suite Variable
Then accessing it in your other test case
