Power Bi report findability ( REPORT CATALOGUE)

Hi all, 

I would like to know the best way to share power bi reports with your colleagues. We have a big number of reports within my organisation and although you can find all the reports in the power bi web I think it is not a very intuitive solution. Basically I need a simple and effective catalogue like a gallery of all the reports. I am investigating sharepoint,  power bi report (rest api) and power apps as a solution.  I will love to hear your thoughts since I don't have experience on the subject and info is scarce online
