Add Spring security authentication to React

Question

I have a project with built-in spring security athentication that works fine. Now I'm rewriting the frontend from jsp to react and I need authentication to work for both of them for now. So, if credentials is correct, spring returns my jsp index.jsp page, otherwise error.jsp page.

How can i apply this logic to react?

My configuration:

<sec:http auto-config="true" use-expressions="true" access-decision-manager-ref="accessDecisionManager">
            <sec:intercept-url pattern="/login" access="permitAll"/>
            <sec:intercept-url pattern="/test-alive/*permitted/**" access="permitAll"/>
            <sec:intercept-url pattern="/pinChanged" access="permitAll"/>
            <sec:intercept-url pattern="/changePassword" access="permitAll"/>
            <sec:intercept-url pattern="/**" access="isAuthenticated()"/>

            <sec:form-login login-page="/login"
                            authentication-success-handler-ref="loginSuccessHandler"
                            authentication-failure-handler-ref="loginFailedHandler"
                            authentication-details-source-ref="rsaDetailsSource"
            />

            <sec:logout logout-url="/logout" invalidate-session="true" success-handler-ref="logoutSuccessHandler"/>

            <sec:csrf request-matcher-ref="csrfSecurityRequestMatcher" token-repository-ref="tokenRepository"/>
            <sec:session-management>
                <sec:concurrency-control session-registry-ref="sessionRegistry"/>
            </sec:session-management>
            <sec:access-denied-handler error-page="/access-denied"/>
</sec:http>
