Hi! I'm trying to create an adaptive card with typeahead function using a PVAbot since my goal is to search a long list of options. I used the below link as my guide but upon testing, the card renders but the typeahead function does not work (it just appears as a list which you need to scroll down).

Reference output:

Actual Result (free text disabled for the search bar):

I've read that the typeahead function is available in version 1.5 so I tried replacing the below portion from the template to "1.5" but this results to an error

Error if version is replaced to 1.5:

My current MS Teams version is 1.5.00.33362 (64-bit). Is there a way to make the typeahead function work?
Thanks!
