Starting a coffeeshop, what licenses do I need? “i will not promote”

“I will not promote” I posted here a while ago that I’m planning on starting a coffee shop and I’ve been looking into the licenses and permits we’ll need. I’m completely new to this and trying to understand everything and figure out the paperwork so I can make sure we’re doing it right. We thought about it and decided that it is best to start with a pop up cart first but we’re stuck on the paperwork. Does anyone know of a resource where I can find out what licenses and permits we would need in Texas for a pop up coffee cart? Also, any advice on the supply side or operations as well? Any recommendations or advice would be greatly appreciated!
