H1B, H4 Visa

I am on H1B with xxx employer with yyy client from 2017 to 2018 and then applied extension with same employer, same client and got approval from 2018 to 2021.

Unfortunately my project ended with yyy client on December 27, 2018. And I was on the bench and looking for the projects. My employer xxx paid two months Jan, feb on the bench and terminated my employment in end of feb month.

So I was in the cap gap period of 60 days and my pay role wasn't ran for March month and my previous yyy client called me back with effective date April 22nd 2019, with same xxx employer, same yyyclient, same role, same project on same H1B. And I am now on the on-going project with same yyy client.

Question:

Please let me know what can I exactly explain to visa officer about my job less period from January 1 to April 21?

My XXx employer has ran pay roll for two months(Jan, feb) and end of feb he sent an email saying your employment is been terminated due to not finding another project and I got another option in the gap period but in March month ending I got a phone call from my employer saying your position is confirmed with previous yyy client and again I signed the contract with xxx employer and yyy client.

Please can anyone let me know how can I explain my whole situation at visa officer???
