Setup with Docker Compose inside Portainer

[FuckingToasters]

hello, I'd like to setup btcpayserver inside portainer for which i would need to create an stack with an existing example compose.yml file.
From what i read, it seems like you need to run an script which directly setup the container outside of portainer.

I really appreciate If anyone got an example docker-compose file to share.
