Ring Doorbell automatic live view on Fire tablet

Hello, I do have amazon echo show and fire tablet HD8 (8th gen). Both of them looks like fully supported for alexa skills, but I cannot manage to have live view automatically comming on when dorbell anouncing that "someone is in front...". It is working fine on amazon echo show. When I go camera inside devices setup I see in section "announcement Devices" only echo show device. The fire tablet is set to be in "show mode" all time long. Thanks for help.
