I want to use the remicres/otb-mosaic plugin (https://github.com/remicres/otb-mosaic) in QGIS.
Fig. 1 is the usage introduction given on the webpage.
However I cannot find the function in QGIS after I copied the file "Mosaic.xml" into the QGIS installation path as instructed on the webpage.
How to find the function in QGIS?
