Instructional videos for Bitwarden

I volunteered to teach a weekly class designed to instruct seniors living in an Aging In Place community how to use their iPhones. I have finally convinced them that they need a password manager and after seeing a recent review of password managers on the ProPrivacy website, I wrote the author and asked him which one would be the simplest one for seniors in their 70s and 80s to deal with and he recommended Bitwarden.
I have installed Bitwarden on my iPhone and as I set up an account, I am taking screenshots at each step so I can project them onto a screen and walk “my” seniors through setting up Bitwarden on an iPhone.
My question is, can anyone provide a link to a step-by-step video demonstrating how to set up Bitwarden on an iPhone?
Many thanks.
