SLS supporting schools in lockdown

[overwhelmedbyitall]

Can I ask for help with some research please (at the risk of helping any competitors!)
I have an interview with a School's Library Service and have to give a presentation : 'in another lockdown situation, outline what strategies would you employ to engage teachers with our services.'
It's an internal interview so I know what we did when lockdown happened: really pushed ebooks, did quizzes on twitter, shared loads of author's workshops etc
What I don't know is how effective any of it actually was! Did teachers actually see or use any of it? What would they have preferred we do?
So, it would be really helpful if you could tell me what you know your SLS did this time, what was helpful, what really wasn't and anything which would be helpful in future.
Thank you so, so much!

(Just in case they're sticklers for that kind of thing, it should be Schools or Schools' Library Service OP)

How to access books was a big issue. Ideas for getting kids writing book reviews or in any way engaging with books.
