Motobility for my adult daughter at university. I have MS

I have MS.
I spoke to Motobility about adding my daughter as a named driver for my new Motobility car. She was registered for my old Motobility car . But it's more complicated now.
Motobility said it was ok to do that when l spoke to them on the phone, but she wasn't with me, so l couldn't finish the application.
l need to apply online today (Saturday afternoon ) for it, as she wants to drive my Motobility car tomorrow (Sunday).
She's 21, is registered as living at my home address for voting and when she's not at university.
In your opinions, can l put her down as a named driver? She was a named driver before she went to university. She would only drive locally here to drive me if we were going out, or for driving herself to work.
I chose my current car as it's suitable for under 25 year olds to drive due to its brake horse power
Also l checked with Motobility if she could use the car to drive to work and drive herself back late at night while she's here (to avoid me having to wait to pick her up , staying up late and putting myself in a vulnerable position driving to pick her up around midnight - l have MS)
Motobility said yes over the phone, as it benefits me.
I'm feeling stressed about applying online. Wish l could apply in the week and speak to a person.
** Anyway, has anyone else got their young adult daughters and sons as named drivers and they use the Motobility cars to drive to and from work ? **
With my previous Motobility car it was great to share the driving when we drove her to her university in January. She drove there (six hours with stops) and l stayed overnight and drove back the next day with a couple of stops . Very civilised!
Thanks so much for your help!
