Wix contacts backend does not have .contains

Just building a repeater by querying the wix contacts backend.

The functionality does not have a .contains feature. Only a .startsWith

hhttps://www.wix.com/velo/reference/wix-crm-backend/contacts/contactsquerybuilder

So say if i wanted to query a contact with first name: Dr. Smith. My search text box has to have Dr.
Whereas in a normal wixdata query I can have even “smi” and it will show up the correct result.

Interestingly, in the dashboard section of wix contacts, I can search for “smi” and the correct will pop up.

Why hasn’t this feature been enabled on the velo side?

TIA!
