A quick google search of free online courses will help you
This is one that I found.

It may be worth getting your team to activate in the social media ( digital ) space so
your business remains relevant with your customers ( we have a VIP FB page that all the store managers
interact on daily ) but unless you are cleared to sell as an essential service
content will simply be about engagement.
There are also lot of digital courses on line, that are free, that your team
can look to do, this may assist you moving forward, as we will all need to be a lot more relevant on digital
platforms for a while to drive income.
