For the moment, you will be unable to make any transactional actions regarding your investments and pensions within the Bud app. In order to do so, you can click the 'Go to your x account' button to be redirected to your providers website or app to make the actions there.
Making transactions within the Bud app could be possible in the near future. If you would like to have a payment capability directly in the Bud app, let us know by submitting your interest here: https://forms.gle/6C7YEwHy42WegJKy8 (for investments) and https://forms.gle/HKbXEaKQWo6bYQHM7 (for pensions). If there is enough interest, it may be on the cards for sooner than you think!
