TextMesh Pro How to properly get TMP links from TMP_Input?

Do I get them from the parent Input or the child UGUI ? I may be able to answer my own question soon, but I'm having a strong feeling from initial tests that BOTH answers are wrong -- maybe finding the intersection on a TMP_Input requires additional steps?

I got this working fine on a regular UGUI, but haven't issues with TMP_Input.



(^ typeLink style worked in a regular UGUI)

EDIT: I noticed txtInput.textComponent != UGUI: it's a TMP_Text -- does this make a diff?

EDIT 2: Tried txtInput.textComponent.GetComponent<TMP_InputField>() found from here to specifically get the UGUI to test a difference. Nah didn't work so tried this way + finding the link from the UGUI child -- both no dice. Seems like there's something weird going on with TMP_INPUT's that don't allow links. Would love a workaround or advice
