Seems like duplicate of #2793 but that one got locked.

I think this would position drawio a lot in the Salesforce ecosystem since the only diagraming tool that currently support the shapes is Lucidchart (it could eventually be listed in the Salesforce Diagram Kit of Parts to gain tool visibility).

Miro has also added support for Salesforce diagraming library, although only on paid plans

@jonathanwiesel we don't care who adds what or what other tools do. These are off-topic.

@davidjgraph just wanted to share it since knowing what the competition does for the same request / requirement gives a better understanding of the audience, needs and positioning of a feature in the product which also helps in priorization.

However if you don't find it useful or consider it harmful I'll avoid sharing in that regard, was not my intention to generate conflict
