Older available versions of Fusion can be downloaded from the VMware downloads site. It can be a bit challenging to navigate, though.
First use the information in the article https://kb.vmware.com/s/article/2088571 to determine which versions of Fusion are supported on 10.15 Catalina.
Then go to https://downloads.vmware.com and scroll down until you find VMware Fusion under the Desktop & End-user Computing category.
Click on the Download Product link.
You'll be directed to the "Download VMware Fusion" page. Use the drop-down box to select the major version you've interested in. Hint: Minor versions such as Fusion 12.1, 12.2, and 13.5 are major versions 12, 12, and 13, respectively.
Once you've selected the desired major version, the latest minor version and update are displayed. Don't worry, that you only see the latest minor version/update - keep going from here.
Click on "Go to Downloads" next to the shown version. That will take you to a "Download product" page.
The "Download Product" page has a "Select Version" drop-down. All versions of the product for that major version should be listed. Select the desired version and it will appear in the panel. Then click the "Download Now" button to download that version
