On the other hand, the documentation is quite lacking, and there doesn't seem to be much discussions around that (I had very little with Stackoverflow for example).
This got me wondering, I am the only one doing that sort of stuff? I counted 99 plugins on Gmail marketplace, about half being specific to a product rather than general-purpose.
I'm also wondering about transforming that as a side-business: the 2 NGO I have good insight into have hugely inefficient process to fill their opening hours with volunteers, leading to burnout of the team who handles that booking.
As anyone turned that sort of opportunity around Gmail plugins in a business?
My understanding is that too many people were abusing the system and they had to put tougher acceptance processes in place to protect their users.
