Clicking and Dragging Items in Safari Pages (Online Whiteboard Apps)?

I am a Noob but think that KM might be able to let me automate several whiteboard apps (such a Google Jamboard, Padlet, Miro and others),

I want to be able to drag an object that is visible on screen in Safari to another location on the same page. I can select the object with a mouse click. The webpage allows me to do this but how can I create a macro to make this happen automatically?

Any help gratefully received?

Nice! What have you tried so far? Which part are you getting stuck on? Screenshot our link to an example page of what you are trying to do?
