Hello @jans.delossantos
By App, do you mean UiPath Studio or UiPath Apps?
By your description I think you mean Studio, and in that case you could simply tap New Project which creates a simple sequential process by default.
Here you could add more separate workflows (eg. sequence files) and split your code up into natural “bits”, or keep it all in the main sequence/file.
When becoming a bit more familiar with the software you could try out the built-in template for the UiPath Robotic Enterprise Framework (REFramework) that supports a more advanced transactional type automation.
