Are there any resources or conversations on using Wix CRM?

Hi all! I’m a CRM administrator. I have a small nonprofit client interested in investing in a CRM and they’re currently using Wix for their website. After some digging, I see that Wix has a CRM but limitations on creating custom objects for donor tracking. Does anyone have any tips or recommendations for tracking donations using Wix? I’m mostly stuck on how I can manually enter donations if paid by check.

I think there were some apps on App Market related with donation but I don’t if it’s supports features you need.
