Webinar resources - pdf file

My organization is new to Zoom. We have the Zoom webinars subscription, WITHOUT the webinar resources option. With the webinar software we had previously, we were able to upload a pdf document during meeting set up so that all attendees could access no matter when they joined the call. We no longer have that option. Does anyone have a solution for sharing a link to a pdf file DURING a webinar? We can share it in the chat, but I don't want to have to share it multiple times throughout the webinar for people that login late. Any advice you can provide is helpful!
