Preview Generator on a hosted account

Hello folks,

my Nextcloud installation is running on a hosted account at, because I’m not too knowledgeable when it comes to linux etc.
Is it possible for me to run a cronjob with this? I can only use Webcron as it looks like.
And I don’t have access to the prompt on my hosted account.

Thank you for your help and sorry for my bad english.


EDIT: I just read that you cant use webcron. Bummer. Guess it wont work. @mod: can be closed/deleted.
