LinkedIn Carousel implementation

You can upload a Carousel on the LinkedIn platform by uploading a PDF.
We thought about simplifying the process without breaking your workflow.
Just upload images as you have already done, and in the LinkedIn settings, mark it as "Post as images carousel."
Postiz converts it to a PDF in the background and posts it to LinkedIn.
