how to specify `--sidecar` path?

[mooseyboots]

hi, i'm just getting used to using workflow_ocr in my nextcloud.

i'd like to use the --sidecar argument with ocrmypdf: it outputs a text file of the OCR result alongside the pdf. it takes a path parameter, which i don't know how to provide. i have tried both output.txt and ./output.txt, and neither work, i suspect because the command is run somewhere under /tmp. is there a way to provide a path parameter relative to the current nextcloud path?

thanks!
