What am I doing wrong?

I'm trying to wait for browser to see the first part of a string using:

            ltext = f"Page {sw['current_page']}"
            element = WebDriverWait(self.browser, delay).until( \
                EC.presence_of_element_located((By.PARTIAL_LINK_TEXT(ltext))))

value of sw['current_page'] is 2, so ltext is 'Page 2'
the page text is: 'Page 2 of 76, records 26 to 50 of 1878'
URL: https://bizfilings.vermont.gov/online/BusinessInquire/

receiving the following error:

Error:
Traceback (most recent call last):
  File ".../src/Vermont/ScrapeVermontBusinesses.py", line 178, in <module>
    main()
  File ".../src/Vermont/ScrapeVermontBusinesses.py", line 175, in main

    EC.presence_of_element_located((By.PARTIAL_LINK_TEXT(ltext))))
TypeError: 'str' object is not callable

Waiting on Partial text is new to me, what am I doing wrong?
