Button with pop up form

[sergiogallegos]

Hi, How can I make a button that comes with my store's theme have the feature to open a pop up form? It only allows me to add a site page or URL.

I add a photo of a section of my site where one of several buttons appears that I intend to work that way. The client would request a quote for his project by clicking the "Solicitar cotización" button and filling out the form. The form would be generated in the CRM Pipedrive.

Thank you so much.
