Missing dividend information for OTC stocks

[flux77]

Dividend information via the "Dividends v3" endpoint is completely missing for OTC stocks. For example, Roche Holding Ltd (RHHBY), First National Bank Alaska (FBAK), and OTC Markets Group Inc. (OTCM) are consistent dividend-payers, but their dividend information is completely missing.

As a concrete example of the omission, First National Bank Alaska declared a dividend of $3.20 per share on 2022-07-28 (source: First National Bank Alaska Declares Dividend For Third Quarter 2022), but that information is missing in Polygon.io.
