Can't set charges within chemfig #22

Using say \chemfig{A^+-[2]B} which should look like:

however it fails to display. It seems like the support for adding charges to atoms is lacking, including the \charge macro

It looks like the packaged tikzjax just ships an old version of chemfig, where \charge wasn't available. Using \listfiles in the preamble and looking into the console:

chemfig.sty    2019/04/18 v1.4 Draw molecule with an easy syntax (CT)

Temporary workaround is to use the \lewis command, which was deprecated in chemfig 1.5 on 2020-03-05 and removed in chemfig 1.6 though.
