What are my next steps, now that we got the initial approval email?

We applied for GV by investing in a IMGA AƧƵes Portugal A Fund during last week of dec 2021. Couple of days ago my attorney forwarded this email for 3 of us

Informamos que, em 18-09-2023, foi admitida a candidatura de AutorizaĆ§Ć£o de ResidĆŖncia de Investimento (ARI) a My Name, nacional de ƍNDIA
A partir desta data poderĆ” proceder ao agendamento da sua deslocaĆ§Ć£o a um posto de atendimento do ServiƧo de Estrangeiros e Fronteiras.

Couple of questions:

  • We live in canada with indian passport, is there anything we need to do now while we wait for biometrics appointement?
  • The approval included me, my wife and my son but they are asking for proof that we support my wifeā€™s mother. What documents can we provide to prove that she is dependent on us? My wife has no siblings and her father passed away few years ago.
