Vault Framework SDK Plugin: Scaping commas in framework.TypeCommaStringSlice

Hi there, Hashicorp

Is there a way to read the values provided in an attribute that is type framework.TypeCommaStringSlice with commas inside the string? Pretty much I’m looking forward to do like the following:
"'custom=vaultTest,bob@company.com,alice@company.com',key1=item2,keyMulti=tier1,keyMulti=tier4"

And then result in code would be:

stringSlice → [ “custom=vaultTest,bob@company.com,alice@company.com”, “key1=item2”,“keyMulti=tier1”,“keyMulti=tier4”]
