How to use the matrix-js-sdk.EventStatus.SENT function in matrix-js-sdk

export function isContentActionable(mxEvent) {
    const { status: eventStatus } = mxEvent;

    // status is SENT before remote-echo, null after
    const isSent = !eventStatus || eventStatus === EventStatus.SENT;

    if (isSent && mxEvent.getType() === 'm.room.message') {
        const content = mxEvent.getContent();
        if (
            content.msgtype &&
            content.msgtype !== 'm.bad.encrypted' &&
            content.hasOwnProperty('body')
        ) {
            return true;
        }
    }

    return false;
}
