Helly guys, I have an assistant attached to a workflow. I noticed that default provider is "vapi". But apparently it's impossible to chose another provider like openai when assistant is attached to a workflow. When I try to pick another one from the lsit, I get the empty prompt instead of the worflow Am I missing something ? is it possible to have a worflow works with an assistant attacheed to openai or to another model ? https://cdn.discordapp.com/attachments/1211484481848873020/1371497475290042538/Screenshot_2025-05-12_at_16.37.16.png?ex=68235a0f&is=6822088f&hm=e300e85e61b56f780c3950ba73982386772b4bb893f45403c3449285b9d77b72&
