Daughter of a great saint

Peace and blessings to the rabbi
I know a woman who is the great-granddaughter of one of the great Admorims, the late Z"A.
As a child, she would go to the synagogue that her grandfather had donated and built, and she would pray with him, and she loved it very much.
When she grew up a little, she was told that she could no longer be in the east side of the synagogue with her venerable grandfather, but that she should go up alone to the women's aid and pray from there.
She was upset and hasn't gone to synagogue since.
Today, she does not observe Shabbat and runs a household that is not according to Halacha, although she lights Shabbat candles, etc.
She is a right-wing settler and strongly opposes Netanyahu's corruption and the disasters he is bringing upon the people of Israel, especially when people from the Halach family serve in the IDF and pay with their own flesh some of the price of his inaction.
I learned about a group of protesters against the coup and corruption who have an internal WhatsApp group for organizing demonstrations, and unfortunately some of the messages there are sent on Shabbat, and sometimes some of the demonstrations begin between sunsets or even before sunset on Shabbat (rare), so there is a chance that you will read messages on Shabbat or even be tempted to come to the beginning of the demonstration, which is sometimes between sunsets and perhaps even, exceptionally, right before sunset.
What is certain is that she lives in a place that she has to get to by car, so there is a good chance she will violate Shabbat to demonstrate and try to save the people of Israel. 
I asked her not to desecrate Shabbat because of me, she laughed and didn't commit.
 
Now my questions
She does not observe Shabbat as she normally does, traveling by car for outings, visiting family and friends, etc., although she does not work and lights candles. 
Is it permissible to give her a link to a WhatsApp group that she might open and read messages on Shabbat?
And maybe drive to protest before the end of Shabbat. 
And maybe it is even permissible to demonstrate while desecrating the Sabbath in order to save the people of Israel from the disasters and devastation that Netanyahu is dragging us into.
And another question 
Isn't it better to keep quiet about girls (up to what age?) who come to pray beautifully in the synagogue and not send them alone to help women, because in the end they stop coming, desecrate the Sabbath, and establish a home that does not observe the Sabbath?
 
I would be happy to hear from His Eminence the Rabbi.
Thank you very much.
