I can't find the TFWKID to complete the coordonate widget of the webapp builder with the coordonaite system"RGF93 Lambert 93 (2154)", used in France.
Furthermore, I found the TFWKID to do the transformation of the other way : RGF93 Lambert 93(2154) to WGS84 (4326) wich is 1671.
I tried with this code even if it's not the wright way but it was unsuccessful, the coordonates seemed to be wrong.
The ESRI documentations :
https://desktop.arcgis.com/en/arcmap/10.7/map/projections/pdf/geographic_transformations.pdf
and https://developers.arcgis.com/rest/services-reference/enterprise/8b5045617df52f5290390907b7df768c/gt...
don't include what I'm looking for.
Could you help me?
Thank you.
