Map from wikimedia.org is not showing

I installed the plugin, brought up the field, but then wikimedia.org returns 403 for all map slides, screenshot – https://take.ms/EtmOp. In this case, if you follow the link, the slide will open, for example – https://maps.wikimedia.org/osm-intl/14/9904/5123.png

A quick googling of the issue revealed that wikimedia has banned third-party vendors from embedding their maps – https://help.openstreetmap.org/questions/77796/error403-cannot-display-the-map

Is the plugin not working anymore or am I doing something wrong?
