What can I do now I can see Mum in person

Hi everyone! Hope we are all safe and well?

My mum suffered a severe stroke over a month ago now. She is comfortable in a rehabilitation centre where they are working on her recovery and her speech is slowly improving. The NHS staff there have been amazing and are so lovely to her, I am in their debt.
The government recently changed the care home guidelines so we are finally able to see her in person rather than over the phone. We had our first meeting today and it was very emotional.
I am very keen to ensure the meetings I have with her a constructive and help aid her recovery. Can anyone help on what they found helpful for them or some techniques I could use or material online I can use? I know each stroke case is different, but I am keen to work on her cognitive ability to enhance the improvements already being made.
