Troubleshooting Salesforce Opportunity List for Clay Integration

I have made a list of opportunities in Salesforce (literally all opportunities) and I can't get it to surface in the list of SF lists, to bring into Clay. It has between 30-90k records, so I know it needs to be SOQL-compatible, and I think it is, but I can't be sure. It's not a complex list it's got 1 filter and it's a public view. Help!!!
