hi i am working on a screen that contain a video player on full screen and a rowlist, focus always stays on rowlist and never goes on video.
and on star/options button press i want to show a dialog box. when the video is in buffering star/options button do what it is programed for but when video is in playing state star/options button press slides a default menu bar that contains some options for cc, volume, etc.

So kindly help me on how to disable this menu show up and show dialog box every time when star/options button is pressed.

here is code for video and rowlist tag that i am using.

        <Video
            id="video"
            translation="[ 0, 0 ]"
            width="0.0"
            height="0.0" />

<RowList
                id="VideosRowlist"
                itemComponentName="VideosRowlistItem"
                visible="true"
                translation="[15, 40]"
                itemSize="[1900, 232]"
                numRows="2"
                drawFocusFeedback="true"
                itemSpacing="[0, 30]"
                rowFocusAnimationStyle="FloatingFocus"
                vertFocusAnimationStyle="FloatingFocus"
                rowItemSize="[[300, 230]]"
                rowItemSpacing="[[25, 0]]"
                showRowLabel="false"
                showRowCounter="true" />

Note: i have tried putting enableUI = false , and also trickplay = false too.
