Polygon mapping using app like Locus GIS and integration with ODK

1. What is the issue? Please be detailed.
Current ODK does not support display of existing polygons tracks on screen to see the overview of mapping exercise plus to avoid duplication of farms.
I was wondering if any workaround like using external apps like LocusGIS can be used together with ODK.
As LocusGIS does not support advanced custom forms for data entry, we use ODK.
Idea of flow is launching LocusGIS from ODK and then once polygon tracking is complete in LocusGIS bring the set of GPS coordinates from LocusGIS to ODK and then save record in ODK along with other metadata.
Is it possible?

2. What steps can we take to reproduce this issue?

3. What have you tried to fix the issue?

4. Upload any test forms or screenshots below.

I bypass the problem. I'm using the data type (https://docs.getodk.org/form-question-types/?highlight=autocomplete#id23) start-geopoint

The "secretly" created GPS points are displayed on the overview map. This also takes you to the form with the already recorded data
Of course, it would be nice if this would work with lines or polygones in the future
