[keycloak-user] User impersonation - JWT

Dears, I need a help with user impersonation on keycloak. I am authenticating users through the "/realms/test/protocol/openid-connect/token". As expected, it returns a token JWT. In my app, all requests go through apiman, which validates the JWT. Now, I need to personification of user. I'm calling the service "/admin/realms/test/users/USER_ID/impersonation", sending the token in the header (Authorization = Bearer eyJhbGciOiJSUzI1NiJ9 ...). The service /impersonation creates the user session on keycloak, however doesnt return a JWT, but 3 cookies. *I'd like to get the JWT of personified user instead of cookie.* It's possible?
