DMA Migration assessment suggest CLR as breaking changes

Question

Hello,
I have done Migration Assessment using Database Migration Assistant (DMA) and it suggest something for CLR as breaking changes:
I am planning to migrate from Sql 2012 to Sql 2017 (in place upgrade)

CLR assemblies marked either SAFE or EXTERNAL_ACCESS
Type: Assembly
Name: SAPCLR

When CLR Strict Security is enabled, attempting to create an unsigned assembly will cause an error

I was looking into Database and found following:

When I run sys.assemblies it gives me following:

microsoft.sqlserver.types.dll

If I ignore it and migrate, it will hurt anything?
How to find any CLR function using into database?

Thanks for your help!
