How to prompt user for saved e-signature when clicking on the e-signature field?

Bumping this question. I am running into the same issue with the e-signature field box which is a required field on the form I am reviewing for accessiblity. Is there a setting that prompts a user to select digital signature when using the signature form field?  Or should we eliminate the signature form field all together and instruct users to select fill & sign to add digital signatures? Any guidance is appreciated as I am striking out looking for any answer online. 

Thanks in advance!

?

anyone?

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Acrobat forum so that proper help can be offered.

When I right click the e-sig field box, click on Properties, "Signed tab" nor "Actions" come up. The only tabs in Properties are: General, Appearance, Position, and Options.
