Convert multipage Tiff to PDF on linux/kestrel - .Net core 3.1

Hello,
Our business requirement is to convert multipage tiff image to pdf.
We tried this approach given in this link, but this is not working on linux/kestrel server.

Our services are built in .net core 3.1 and above. So all are hosted on Kestrel.
We tried other approach but its not working for multipage.

Appreciate your help and thanks in advance
