Hello guys! New to this great world of chatbots!

So I am starting some pilots on chatbots and I have a possible job around the corner but I have an important question related to the Meta Business Verification process:

So I asked chatgpt, read lots of forums and also saw lots of videos but I can’t seem to find an answer as to WHO needs to have the Meta Business Verification if I am going to be an “agency” that creates the bot and manages the marketing HSM, etc. of other clients. 

I understand that my agency needs to have the Meta Business Verification, but does my client needs that too? My client already has a Facebook page, IG and will have a Whatsapp number that will have each a similar chatbot but I will create and manage them. Do they need the Meta Verification?

What are the workarounds if they also need to have it?
