Custome XML to Flowable

Hello,

I am currently in the process of integrating a custom XML model into Flowable, along with its associated forms. I have created the model in XML format and am now exploring the best approach to upload it directly into Flowable. Could you please provide guidance on whether there are any APIs available for this purpose? If so, I would greatly appreciate it if you could direct me to the relevant documentation or any demo URLs where I can find more information. Your assistance in this matter would be immensely helpful. Thank you in advance for your support.
